AB  - Potreba za osetljivim senzorima hemijskih, biohemijskih i bioloških agensa u današnjem svetu sve je veća, od industrije, preko biomedicine, do očuvanja okoline i protivterorističke odbrane. MeĎu najosetljivijim i najsvestranijim napravama ove vrste su elektromagnetni senzori, naročito oni koji svoju funkciju zasnivaju napovršinskimplazmonima-polaritonima (surface plasmons polaritons, SPP) na meĎupovršini metal-dielektrik. Sa dolaskom nanotehnologija otvorila se mogućnost da se proizvedu metal-dielektrični nanokompoziti, čime je omogućen novi stepen slobode u dobijanju SPP senzora i stvorena nova grana elektromagnetne optike koja je nazvana plazmonika. Posebno bitan proboj predstavljaju elektromagnetni metamaterijali koji se mogu definisati kao veštačke strukture sa elektromagnetnim, odnosno optičkim osobinama, kakve se ne pojavljuju uobičajeno u prirodi.

Osnovna ideja je da se kontrolisanim strukturiranjem metal-dielektričnih nanokompozita obezbedi projektovanje novih elektromagnetnih modova.

AB  - The need for sensitive sensors of chemical, biochemical and biological analytes in the contemporary world is ever increasing, from industry, to biomedicine, to environmental protection and homeland defense. Among the most sensitive and most versatile devices of this kind are electromagnetic sensors, especially those with their function based on surface plasmons polaritons (SPP) at a metal-dielectric interface. The advent of nanotechnologies ensured a possibility to fabricate metal-dielectric nanocomposites, thus ensuring a novel degree of freedom in the fabrication of SPP and creating a new branch of electromagnetic optics, the plasmonics. An especially important breakthrough are electromagnetic metamaterials that can be defined as artificial structures with electromagnetic or optic properties which do not occur usually in nature. Maybe the best known example are the so-called "left-handed" metamaterials, the structures whose effective refractive index in a given wavelength range reaches negative values.This dissertation is dedicated to a consideration of the applicability of plasmonic metamaterials for highlysensitive sensors of chemical, biochemical and biological analytes. The basic idea is to ensure the design of new electromagnetic modes through controlled structuring of metal-dielectric nanocomposites. These modes are further used to overcome the fundamental limitations of conventional plasmonic sensors and to increase their sensitivity and selectivity.The concept of metamaterial from one side offers an opportunity to engineer the frequency dispersion and thus to design optical modes unattainable in natural materials, while from the other side it allows the modification of the spatial dispersion, i.e. controlled changing of the optical space (the so-called transformation optics). One of the main consequences is the possibility to concentrate the optical field into deep subwavelength domains, which leads to a drastic increase of the sensitivity of chemical, biochemical and biological sensors. Another consequence is the possibility to form plasmonic nanocomposites which by introducing new modes ensure selective readout ofviithe targeted analytes. Finally, the geometry of such structures ensures efficient coupling with a readout beam, which is a large problem with the conventional SPP sensors...

AB  - Realization of intelligent thermal vacuum sensors based on multipurpose thermopile micro-electromechanical (MEMS) chips is presented in this work. These vacuum sensors satisfy the main requirements for contemporary sensors, they are cost-effective in both fabrication and operation, and simple to use. Intelligent devices based on two types of thermal sensors, A-type with Al heater, and Ptype with p(+)Si heater, were developed. Both types have two thermopiles with 30 p(+)Si/Al thermocouples each. Thermal and electrical isolation is provided by a sandwich membrane (residual n-Si and sputtered oxide). The intelligent functionality is achieved by using a signal processing unit the authors developed earlier for pressure sensing based on their proprietary Si piezoresistive pressure sensing elements. The main issues which were of key importance for realization of intelligent vacuum sensors are addressed in this work: design and fabrication of the intelligent vacuum sensors, adaptation of the software module, linearization of the input signal using digital signal processing and temperature compensation. A three-udstage test procedure is presented. The A-type sensor, with a thinner membrane, achieved 19 times better thermopile voltage-pressure sensitivity compared with the P-type sensor, with a thicker membrane. Since the estimated noise level of the measuring system is comparable with the useful signal of the Ptype device, the improved voltage-pressure sensitivity provides a better resolution and signal to noise ratio of the intelligent vacuum measuring system.

AB  - Thin Ni and Cu films with fine-grained structures have been electrodeposited from self-made sulphamate-based and sulphate-based electrolytes, respectively. DC electrodeposition of Ni films was performed on single crystal Si wafers with different orientations named (100) and (111), and electrodeposition of Cu films was performed on massive electrodeposited Ni films as the substrates. In order to investigate the influence of the microstructure of the substrates and Ni and Cu thin films on mechanical properties of these composite structures, Vickers microhardness testing for different loads was done. For any composite system of thin film on a substrate, there is a critical indentation depth,1 when a measured hardness value is not the hardness of the electrodeposited film, but the so-called "composite hardness", because the substrate also participates in the plastic deformations during the indentation process. Composite hardness model of Chicot-Lesage was chosen and applied to the experimental data in order to analyse and determine the absolute film hardness. Further analysis of work hardening parameter (t/d)m, that can express the difference in tendency of the composite hardness with the indentation load, was performed for the above-mentioned composite systems.

AB  - Monolayer adsorption-desorption processes at the surface of plasmonic sensors are modeled, first in an exact way, as a nonlinear second-order reaction, and then, after some approximations justified from the practical point of view, as a first order linear reaction. The time evolution of the number of adsorbed molecules from the beginning of the process to the moment in which the system reaches its equilibrium is derived in both cases. A comparative analysis of transients and steady state response is performed for a plasmon sensor with gold surface for some saturated and cyclic hydrocarbons including benzene, as well as for carbon monoxide. The results show in which practical situations the simpler linear model can be used and when the nonlinear model of adsorption-desorption must be applied instead.

AB  - Different composite systems of electrodeposited monolayered and multilayered thin metal films of Ni and Cu on cold-rolled copper substrates were made. Thin metal layers were deposited at narrow spacing of 300 nm and 150 nm and high strength of composites was obtained. Microhardness analysis was performed on the systems of ED Ni film (sulphate "Slotonik 20" electrolyte) / ED Cu film (sulphate electrolyte), ED Ni film (sulphamate electrolyte) / ED Cu film (sulphate electrolyte) and ED Ni film (sulphamate electrolyte) /ED Ni film ("Slotonik 20" electrolyte). Characterization of mechanical properties of the composite systems was done using Vickers microhardness testing with loads ranging from 0.049 N to 1.96 N. Dependence of microhardness for different composite systems on microstructure and Ni/Cu and Ni/Ni layer thickness ratio was investigated. Composite hardness model of Korsunsky was applied to the experimental data in order to determine the absolute composite film hardness. The highest value of all the composite film hardness values was obtained for the system of multilayered Ni films from two different electrolytes, and "Slotonik 20" and sulphamate and with sublayer thickness ratio 1:2, respectively.

The goal of this investigation is to determine the effects that mechanical deformation occurring in real applications can have on electrical parameters of metal interconnects in flexible electronic circuits. The thickness of thin film gold conductors is of the order of 10 nm. while their lateral dimensions are in the micrometer range. Electrical parameters of thin film conductors are measured under uniaxial tensile stress and in the relaxed state after subjecting them to a number of stretching and relaxation cycles. SEM imaging of the test structures was used for observing of possible changes in thin film surface morphology caused by the applied tensile stress.

Using the derived expressions the analysis is performed in order to estimate the influence of mass transfer on the equilibrium fluctuations of the measured signal. The results show that mass transfer significantly influences the spectrum of fluctuations. The theory is useful for determination of limiting performances of cantilever sensors and for characterization of molecular binding-unbinding interactions using measured fluctuations in the sensor's signal.

The derived theoretical model of the fluctuations takes into account the mass transfer effects. The numerical calculations show that when the mass transfer is slow, the low-frequency amplitude and the corner frequency of the Lorentzian AD noise spectrum obtained by derived expressions are significantly different compared to the same parameters predicted by the model that neglects mass transport effects. The presented analysis enables good estimation of these parameters from the measured noise spectrum, which is important because they are used as the source of information about the analyte concentration and the kinetics of biomolecular interactions.

AB  - We derived a simple theory of fluctuations of the equilibrium number of adsorbed molecules in biosensors, caused by the stochastic nature of adsorption-desorption (AD) processes coupled with mass transfer. The two-compartment model is used for approximation of the spatial dependence of analyte concentration in the reaction chamber, which is justified when a thin layer depleted of the analyte exists close to the surface on which the binding reaction occurs. By using the obtained analytical expression for the power spectral density of fluctuations we perform for the first time the quantitative analysis of the influence of the mass transfer on the fluctuations spectrum. For realistic parameter values, the influence of mass transfer proved to be significant, causing the increase in the fluctuations level of up to two orders of magnitude compared to the rapid mixing case. The dependences of the mass transfer influenced fluctuations spectrum on various parameters of the analyte-receptor binding process are also systematically investigated. The presented theoretical model of fluctuations enables good estimation of the AD noise, which affects the total noise and the minimal detectable signal of biosensors. It provides the guidelines for improvement of the limits of detection, and for optimization of detection methods. The theory is also proposed as a basis for development of highly sensitive methods for analyte detection and characterization of biomolecular binding processes, based on the measured fluctuations spectrum. It is applicable for various types of sensors whose operation principle relies on the adsorption process of analyte molecules.

The presented theoretical model of fluctuations enables good estimation of the AD noise, which affects the total noise and the minimal detectable signal of biosensors. It provides the guidelines for improvement of the limits of detection, and for optimization of detection methods. The theory is also proposed as a basis for development of highly sensitive methods for analyte detection and characterization of biomolecular binding processes, based on the measured fluctuations spectrum. It is applicable for various types of sensors whose operation principle relies on the adsorption process of analyte molecules.",

AB  - Characterization of adsorption-desorption (AD) processes of gas particles on semiconductors is necessary in order to investigate the influence of these processes on the micro/nano-devices performance. By applying a numerical computational method we determined the pressure dependence of the equilibrium coverage of the semiconductor surface by chemisorbed gas particles. We concluded that the pressure dependence of the total coverage of the surface by adparticles, and also of coverages by both the neutral and ionized adparticles, can be obtained by measuring the adsorbed mass. We propose the use of nanocantilever sensors for such extremely sensitive mass measurements. The obtained adsorption induced cantilever's resonant frequency shifts are higher than the detection threshold set by the termomechanical noise. This confirms the applicability of the used nanocantilever sensor for experimental characterization of AD processes at semiconductor surfaces.

AB  - We investigated a structure for surface plasmon-polariton-based chemical sensing consisting of a square 2D lattice of circular nanoapertures drilled in a plasmonic material on a dielectric substrate. Contrary to the usual approach, we did not consider opaque metal slabs, but instead investigated a thin film of transparent conductive oxide (TCO) as the plasmonic part. Thus we ensured a simultaneous use of activity of the TCO as chemical sensing material and of its Drude-type plasmonic behavior. The nanoaperture arrays in this case serve a dual function of a tunable plasmonic guide and of a grating-type coupler between surface plasmon plaritons and propagating modes. We performed FEM electromagnetic simulation of our structures used as sensors for the case of indium tin oxide (ITO). The proposed scheme exhibits a monolayer sensitivity to chemical or biological agents and is comparable to the previously proposed plasmonic sensors, including those based on extraordinary optical transmission nanoaperture arrays. It may seem surprising that the transmission difference caused by the presence of analyte was comparable to the values found in equivalent structures utilizing opaque metal. Lower absorption losses ensure higher overall transmission through the nanoaperture array and decreases the tunable transmission range, but simultaneosly opens a path toward the use of the proposed approach in alternative geometries, for instance for in-plane propagation utilizing endfire coupling.

It is based on unification of results obtained using the already developed two-zone analytical model and theory of laminar fluid flow over uniformly heated plate. This model can be used in order to extract the main parameters for various geometrical configurations of thermal flow sensors. Presented analytical model was further verified by experimental results. Flow tests were performed using multipurpose MEMS flow sensors consisting of two thermopiles, with 30 p(+)Si/Al thermocouples each, and a "U" shaped p(+)Si heater. Thermally isolating membrane was formed of sputtered SiO(2) and residual n-Si layer. Experimental evaluation was performed under various flow conditions and applied heating power values. The results showed excellent agreement with theoretical predictions.
