Photolysis of Steroidal 20-Aryl-Substituted 11-Nitrites
(Wiley, 1997)
The two structurally similar 20‐phenyl‐ and 20‐(4‐methoxyphenyl)‐11‐(nitrosooxy)pregnan‐20‐ol derivatives 4 and 7 behave differently under photolytic conditions, the former nitrous acid ester affording, as a main product, ...
Photoacoustic investigation of thermal and transport properties of amorphous GeSe thin films
(AIP Publishing, 1994)
In this work the possibility of simultaneous determination of thermal and transport properties of thin films using a photoacoustic method was investigated. The properties of amorphous GeSe thin films, which were evaporated ...
Optical properties of guanidinium aluminium sulphate hexahydrate (GASH)
(IOP Publishing, 1993)
Far-infrared reflection spectra were determined, for the first time, for single crystals of guanidinium aluminium sulphate hexahydrate (GASH) and its solid solution for 5 mol.% chromium isomorph (GCSH). The infrared active ...
Photoacoustic investigation of transport in semiconductors: Theoretical and experimental study of a Ge single crystal
(The American Physical Society, 1995)
Photoacoustic (PA) heat-transmission measurements were used to study transport in a nearly intrinsic Ge single crystal. A theoretical model was developed which quantitatively describes excess carrier and thermal-wave space ...
Photoacoustic frequency heat‐transmission technique: Thermal and carrier transport parameters measurements in silicon
(AIP Publishing, 1995)
Photoacoustic frequency heat‐transmission technique is used to study thermal and carrier transport properties in low‐doped silicon wafers. Amplitude and phase photoacoustic signals as a function of modulation frequency of ...
The ωσ method: A new contactless comparison method for measuring electrical conductivity of nonferromagnetic conductors
(AIP Publishing, 1997)
A novel, very simple, eddy current method for measuring the electrical conductivity of nonferromagnetic conductors is described. This method is relative, i.e., we measure the ratio of conductivities of two samples of the ...
A photoacoustic investigation of transport properties and thermal diffusivity of InSb single crystals
(Elsevier, 1996)
Thermal and electronic transport properties of low-doped single crystal InSb were determined for the first time and analyzed using a photoacoustic frequency heat transmission technique. The thermal diffusivity, excess ...
Anisotropy in Thermal and Electronic Properties of Single Crystal GeSe2 Obtained by the Photoacoustic Method
(The Japan Society of Applied Physics, 1998)
Anisotropy in the thermal and electronic properties for two directions of a thermal wave propagation in GeSe2 single crystal was investigated using the photoacoustic frequency transmission technique. First, the electric ...
Planar Thick Film Integrated LCV Cells
(Emerald Group Publishing Limited, 1995)
New thick film devices were developed to integrate thick film planar inductors L, capacitors C and varistors V into single hybrid devices called thick film planar LCV cells. The first thick film planar LCV cells were printed ...
Transport properties of carriers in GaAs obtained using the photoacoustic method with the transmission detection configuration
(IOP Publishing Ltd, 1996)
Electron transport properties of single-crystal GaAs were determined using the photoacoustic method with the transmission detection configuration. The excess-carrier lifetime, the front and the rear recombination velocity, ...
