Properties of ZnO layers deposited by ''photo-assisted'' spray pyrolysis
(Elsevier Science Bv, 1996)
Layers of ZnO have been deposited onto glass substrates by ''photo-assisted'' spray pyrolysis using zinc chloride and zinc acetate as precursors in aqueous and non-aqueous solutions. The structure of these films has been ...
Comparative study of ZnCr2O4-K2CrO4 ceramic humidity sensor using computer controlled humidity measurement set-up
(Elsevier Science Sa, 2006)
A home-made ZnCr2O4-KCrO4 ceramic humidity sensor was studied using a commercially available reference humidity sensor, SHT75 from Sensirion. The main advantages of our developed set-up for humidity measurements are low ...
Effect of thickness of liquid crystalline layer on the thermotropic and thermodynamical properties of nematic-isotropic liquid and istropic liquid-nematic phase transitions
(World Scientific Publ Co Pte Ltd, 2006)
In this work, effect of thickness of the liquid crystalline layer on the morphologic, thermotropic and thermodynamical properties of the nematic-isotropic liquid and isotropic liquid-nematic phase transitions in Shiff based ...
The effects of air, oxygen and water exposure on the sub-bandgap absorption, the electronic conductivity and the ambipolar diffusion length in highly crystalline microcrystalline silicon films for photovoltaic applications
(Springer, 2020)
Reversible and irreversible changes due to long term air and short term de-ionized water (DIW) or pure oxygen exposure were investigated in about 1 mu m thick hydrogenated microcrystalline silicon (mu c-Si:H) films deposited ...

Forward and reverse current-voltage-temperature characteristics of a typical BPW34 photodiode
(Pergamon-Elsevier Science Ltd, 2006)
The dark forward and reverse current-voltage characteristics of a typical BPW34 silicon photodiode have been investigated in the temperature range 80-300 K. We propose that tunnelling enhanced recombination at or close to ...
Simulation for capacitance correction from Nyquist plot of complex impedance-voltage characteristics
(Pergamon-Elsevier Science Ltd, 2008)
The impression of series resistance on unipolar semiconductor device's capacitance-voltage spectrum is discussed by conventional impedance and admittance analysis, and it is shown that series resistance may cause large ...
Thermo-morphological properties of the smectic C* mesophase in new chiral salicyaldimine liquid crystals
(Wiley-V C H Verlag Gmbh, 2008)
Specific textures and their temperature transformations in large temperature interval for the chiral smectic C* mesophase of new liquid crystalline materials, synthesized by our group, have been investigated in detail. ...
Tunnelling enhanced recombination in polycrystalline CdS/CdTe and CdS/Cu(In,Ga)Se-2 heterojunction solar cells
(Pergamon-Elsevier Science Ltd, 2005)
This article investigates the results of current-voltage measurements made at different temperatures on vacuum deposited ZnO/CdS/Cu(In,Ga)Se-2 and CdS/CdTe heterojunction solar cells. We propose that the current-voltage ...
Room temperature I-V and C-V characteristics of Au/mTPP/p-Si organic MIS devices
(Edp Sciences S A, 2018)
The room temperature electrical characteristics of the organic Au/mTPP/p-Si device fabricated by spin coating method were investigated with I V and C V measurements. It has been determined that the device has a high ...
