Anchoring transitions in nematic-discotic lyotropic mesophase under magnetic field
(Natl Inst Optoelectronics, 2015)
Magneto-morphologic and orientational properties of the lyotropic nematic-discotic N-D mesophase have been studied by the polarizing optical microscopy technique. Texture transformations from the schlieren texture to the ...
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 ...
The effects of native and light induced defects on optoelectronic properties of hydrogenated amorphous silicon-germanium (a-SiGe:H) alloy thin films
(Springer, 2010)
Effects of native and light induced defects states in hydrogenated amorphous silicon-germanium alloy thin films with different Ge concentrations have been investigated by using steady-state photoconductivity, dual beam ...
Investigation of meta- and in-stability effects in hydrogenated microcrystalline silicon thin films by the steady-state measurement methods
(Canadian Science Publishing, Nrc Research Press, 2014)
Metastability effects because of atmospheric exposure, high purity gasses, and deionized water in hydrogenated microcrystalline silicon thin films with different crystalline volume fractions were studied using well accepted ...
Comparative investigations of the thermotropic and optical refractive properties in micellar isotropic phase and nematic-calamitic mesophase of hexadecyltrimethyl ammonium bromide/water and hexadecyltrimethyl ammonium bromide/water/1-decanol lyotropic liquid crystalline systems
(Springer, 2015)
We report the thermotropic properties and measurements of the temperature and concentration dependences of the refractive index in isotropic micellar L (1) phase and nematic-calamitic N (C) mesophase of the hexadecyltrimethyl ...
Investigation of metastability and instability effects on the minority carrier transport properties of microcrystalline silicon thin films by using the steady-state photocarrier grating technique
(Canadian Science Publishing, Nrc Research Press, 2014)
Metastability effects in hydrogenated microcrystalline silicon thin films due to air, high purity nitrogen, helium, argon, and oxygen were investigated using temperature-dependent dark conductivity, photoconductivity, and ...
In vitro biocompatibility of plasma-aided surface-modified 316L stainless steel for intracoronary stents
(Iop Publishing Ltd, 2010)
316L-type stainless steel is a raw material mostly used for manufacturing metallic coronary stents. The purpose of this study was to examine the chemical, wettability, cytotoxic and haemocompatibility properties of 316L ...
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 ...
Temperature Dependent Electrical Transport in Al/Poly(4-vinylphenol)/p-GaAs Metal-Oxide-Semiconductor by Sol-Gel Spin Coating Method
(Hindawi Ltd, 2016)
Deposition of poly(4-vinyl phenol) insulator layer is carried out by applying the spin coating technique onto p-type GaAs substrate so as to create Al/poly(4-vinylphenol)/p-GaAs metal-oxide-semiconductor (MOS) structure. ...
