Investigation of interface and surface energy states in semiconductors by PA method
(European Physical Journal: Special Topics, 2008)
The photoacoustic (PA) signal should generally change with the extent of damage, in the form of surface energy states (SES) or interface energy states (IES). For a mechanically, chemically or particles processed (Ar-plasma ...
Metal-dielectric photonic crystal for the enhancement of solar-blind ultraviolet silicon photodiodes
(Institute of Electrical and Electronics Engineers Inc., 2008)
We report the fabrication of metal-dielectric photonic crystals as bandpass filter for the UV riadiation with a sidelobe suppression in excess of 4 orders of magnitude. The metal-dielectrics were designed for the enhcancement ...
Optimization of micro/nanooscillator parameters for analysis of transient adsorption processes
(Institute of Electrical and Electronics Engineers Inc., 2008)
We consider optimization of parameters of micro/nanooscillators intended for investigation of adsorptiondesorption (AD) processes, which are fast in comparison with the response rate of the oscillator itself. We consider ...
Fabrication and characterization of AFM golden microcantilevers and measurement of small electromagnetic forces
(Institute of Electrical and Electronics Engineers Inc., 2008)
This paper presents results of research oriented towards developing a method for measurement of small electromagnetic forces using atomic force microscope (AFM). The method is based on the measurement of cantilever deflection ...
Non-contact measurement of thickness uniformity of chemically etched Si membranes by fiber-optic low-coherence interferometry
(Institute of Electrical and Electronics Engineers Inc., 2008)
In this paper we present a contactless technique for thickness measurement of chemically etched Si membranes. This technique is based on low-coherence interferometry performed by single-mode fiber-optic sensing configuration. ...
Investigation of silicon anisotropic etching in alkaline solutions with propanol addition
(Institute of Electrical and Electronics Engineers Inc., 2008)
Different propanol isomers additives to 26 wt. % KOH water solution have been studied. It was stated that addition of both isomers result in changing etching anisotropy of (110) oriented corners on Si LT 100 >. For the ...
Photoacoustic elastic bending method: Investigation of the surface recombination states
(26th International Conference on Microelectronics, Proceedings, MIEL 2008, 2008)
The recombination processes of surface modified Si samples by the PA elastic bending method were investigated. The experimental PA elastic bending signals were measured by using special constructed PA cell (the gas-microphone ...
A consideration of optical noise figures of adsorption-based nanophotonic sensors
(Institute of Electrical and Electronics Engineers Inc., 2008)
We consider some intrinsic noise mechanisms appearing in nanophotonic sensors based on plasmonic structures and surface plasmon-polaritons. We analyze the photonic Johnson-Nyquist fluctuations and the adsorption and ...
Metal nanowire arrays with ultralow or negative effective permittivity for adsorption-based chemical sensing
(Institute of Electrical and Electronics Engineers Inc., 2008)
We investigated wire-mesh media with plasma-like dispersion of dielectric permittivity as a potential medium for nanoplasmonic sensors utilizing adsorption of chemical, biochemical or biological analytes. Such structures ...
Photothermal vibration spectra of square diaphragm with boss for low-pressure sensor
(26th International Conference on Microelectronics, Proceedings, MIEL 2008, 2008)
The low-pressure sensors (IHTM-CMTM, SP-6) with square diaphragms and concentric bosses were investigated by the photothermal elastic vibration method. The photothermal vibrations were optically excited (the focused laser ...
