Modulated Photoconductivity Studies of a-As2Se3 Thin Films
Amorphous As2Se3 Photoconduction recombination lifetime trapping
2010/4/9
Modulated photocurrent measurements in amorphous arsenic triselenide (a-As2Se3) is reported. Particular focus is paid towards photocarrier lifetimes as a function of temperature, and applied electric ...
Test of Anderson-Stuart Model and the "Universal" Conductivity in Rubidium and Cesium Silicate Glasses
Anderson-Stuart Model the "Universal" Conductivity Rubidium and Cesium Silicate Glasses
2010/10/14
An analysis and brief discussion of experimental ionic conductivity s and activation energy EA in the binary rubidium and cesium silicate systems is presented, exemplified on 23 and 30 glasses respect...
The Effect of Preparation conditions on the Growth Rate of Films, the Yield of Precipitated Powder and the DC Conductivity of Polypyrrole
DC Conductivity Conducting Polymers Polypyrrole Quartz Crystal Microbalance Technique
2010/4/12
Polypyrrole (PPy) was prepared by a chemical method by using oxidizing agents ferric chloride and potassium persulphate, both as films and pellets. The effect of various variables-such as aging of the...
Optical Characterization of Chemical Bath Deposited Bismuth Oxyiodide (BiOI) Thin Films
Chemical bath deposition technique Bismuth oxy iodide poultry protection and warming coating solar control and antireflection coatings and solar cells
2010/4/12
Thin films of Bismuth oxyiodide (BiOI) were deposited, using chemical bath deposition techniques. The films were characterized using energy dispersive x-ray fluorescence (EDXRF) and Fourier transform ...
Spin-Dependent Conductance in Nonmagnetic InGaAs Asymmetric Double Barrier Devices
Spin-Dependent Conductance Nonmagnetic InGaAs Asymmetric Double Barrier Devices
2010/10/21
The spin dependence of the conductance of an asymmetric double-barrier InGaAs device is studied within the multiband k¢p and envelope function approximations. The spin-dependent transmission prob...
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 ...
Motion of dark solitons in trapped Bose-Einstein condensates
Motion of dark solitons trapped Bose-Einstein condensates
2010/10/18
We use a multiple time scale boundary layer theory to derive the equation of motion for a
dark (or ‘grey’) soliton propagating through an effectively one-dimensional cloud of Bose-Einstein condensate...
The Structure of Liquid Alloys with Chemical Short Range Order
Liquid Alloys Chemical Short Range Order
2010/4/19
We present a study of the structural properties of liquid binary alloys with chemical short range order starting from the effective interatomic pair potentials. The interatomic pair potentials are der...
In the framework of the three-body approach the A(a,bc)A Coulomb breakup has been investigated. The three-body Coulomb dynamic is taken into account to derive the expression for the reaction matrix el...
