A study on the humidity sensing properties of ZnCr2O4-K2CrO4 ionic conductive ceramic sensor
(Elsevier Science Sa, 2006)
The response to humidity of ZnCr2O4-K2CrO4 ceramic composites formed by solid-state reaction at elevated temperatures is studied. The fired ceramic body, which proved to be mainly constructed from ZnCr2O4 spinel grains, ...
Viscoelasticity, dielectric anisotropy, and birefringence in the nematic phase of three four-ring bent-core liquid crystals with an L-shaped molecular frame
(Royal Soc Chemistry, 2013)
Molecular shape is an important factor in determining the material properties of thermotropic liquid crystals (LCs). We synthesized and investigated several LC compounds formed by asymmetrically bent molecules with a rigid ...
Lattice vibrations of pure and doped GaSe
(Pergamon-Elsevier Science Ltd, 2006)
The Bridgman method is used to grow especially undoped and doped single crystals of GaSe. Composition and impurity content of the grown crystals were determined using X-ray fluorescence (XRF) method. X-ray diffraction, ...
The effect of aging on the dark conductivity and noise in hydrogenated microcrystalline silicon thin films
(Wiley-V C H Verlag Gmbh, 2010)
Aging hydrogenated microcrystalline silicon in air is found to affect both the dark conductivity and the 1/f noise. For a sample with a crystalline volume fraction of 0.39, the conductivity decreased by three orders of ...
Investigation of light induced degradation in hydrogenated amorphous silicon-germanium alloy thin films using temperature dependent photoconductivity
(Wiley-V C H Verlag Gmbh, 2010)
Light induced degradation of undoped hydrogenated amorphous silicon-germanium (a-SiGe:H) alloys with different Ge contents has been investigated using intensity and temperature dependence of photoconductivity between 78K ...
Solvent washing with toluene enhances efficiency and increases reproducibility in perovskite solar cells
(Royal Soc Chemistry, 2016)
We report a simple process for reproducibly fabricating perovskite solar cells. We emphasize that the solvent washing technique is the most practical method for successful uniform crystallization so it facilitates highly ...
Effects of supersymmetric CP phases on chargino-pair production via the Drell-Yan process at the CERN LHC
(Amer Physical Soc, 2004)
We compute the rates for pp annihilation into chargino pairs via the Drell-Yan process taking into account the effects of supersymmetric soft phases, at a proton-proton collider. In particular, the phase of the mu parameter ...
Reflective light modulator based on epsilon-GaSe crystal
(Optical Soc Amer, 2002)
We report the results of investigating a low-voltage, polarization-insensitive, reflective-type modulator based on an epsilon -GaSe crystal and operated at the 1.960-eV line of a He-Ne laser. We demonstrate that the ...
Magnetic properties of La0.65Ca0.30Pb0.05Mn0.9B0.1O3 (B = Co, Ni, Cu and Zn)
(Elsevier Science Sa, 2015)
The La0.65Ca0.30Pb0.05Mn0.9B0.1O3 (A = Co, Ni, Cu and Zn) manganites have been prepared via sol-gel method and sintered at 1100 degrees C for 24 h. The aim of the study was to investigate B-site cation doping effects on ...
Instability effects in hydrogenated microcrystalline silicon thin films
(Wiley-V C H Verlag Gmbh, 2010)
Instability effects on the dark conductivity (sigma(Dark)) and photoconductivity (sigma(photo)) of microcrystalline silicon films with different microstructures deposited on smooth and rough substrates, after exposure to ...
