Exact analytical solution of the diode ideality factor of a pn junction device using Lambert W-function model
(2007)
The paper presents a new analytical method for extracting the diode ideality factor of a p-n junction device using Lambert W-function model and the dark current-voltage data. The extracted values are found to be in good ...
Peculiarities of inversion walls and singular points in oriented textures of nematic mesophase
(Wiley-V C H Verlag Gmbh, 2009)
In this work the nature and peculiarities of the inversion walls and singular points, which can spontaneously arise or can be stimulated in the homeotropic and planar oriented textures of the thermotropic nematogens, have ...
The effects of preparation temperature on the main electrical parameters of Al/TiO2/p-Si (MIS) structures by using sol-gel method
(Springer, 2009)
In this study, the forward bias current-voltage (I-V) and capacitance-voltage (C-V) characteristics of the Al/TiO2/p-Si (MIS) structures derived using the sol-gel method have been investigated and compared at various ...
Observation of negative photoconductivity in (ZnO)(x)(CdO)(1-x) films
(Pergamon-Elsevier Science Ltd, 2009)
In this study, (ZnO)(x)(CdO)(1-x) films were prepared by ultrasonic spray pyrolysis (USP) technique at a substrate temperature of 400 degrees C. X-ray diffraction patterns of the films indicate that the (ZnO)(x)(CdO)(1-x) ...
Determination of defect distribution in a Ga-rich ZnO/CdS/Cu (In, Ga) $Se_2$ solar cell by admittance spectroscopy
(2005)
This article presents a study on the energy distribution of defects in efficient thin film ZnO/CdS/Cu(In,Ga)$Se_2$ heterojunction solar cell by the use of admittance spectroscopy. The capacitance spectra of the device has ...
Admittance and impedance spectroscopy on Cu(In,Ga)Se2 solar cells
(2003)
The present work reports some experimental results on the electrical properties of high efficiency ZnO/CdS/Cu(In,Ga)Se2 heterojunction solar cells. Admittance spectroscopy has been employed for characterisation of the bulk ...
Raman scattering in layered CdInGaS4
(2004)
Raman scattering spectra of CdInGaS4 crystals grown by the chemical transport method were measured at room and liquid-nitrogen temperatures. Band pairs at 29-38, 43-48 and 60-65 $cm^{-1}$ are reported for the first time. ...
Real gamma scattering at TESLA x N collider
(2001)
The proposal for measurement of polarized gluon and quark distributions in scattering of
polarized real y beam on polarized nuclear target have been considered. High energy y beam is
obtained by backscattering of laser ...

Searching for Color Octet Leptons in Lepton-Hadron Collisions
(2003)
We study the resonance production of color octet leptons ${l_8}$ predicted by composite preon models of leptons and quarks at lepton-hadron colliders such as TESLA x HERA,$\mu p$ and Linac-LHC with the energy of about 1-10 ...
