- I am working now on polymers thin films, prepared by different techniques, and planning to include nanofillers with the polymers to improve their behavior and to study the possibility of creation of Nano particle of elements from fly ash of our local industrial.
A different thickness of CdTe thin films were prepared from high purity Cd and Te blended powders and by the way of thermal evaporation technique at a vacuum of 2 10 5 mbar. Thin films were prepared on cleaned glass substrates at room temperature. The X-ray diffraction patterns for as prepared samples have an amorphous structure. The optical energy...
Vacuum alloying system was designed and built up to alloy (Te61.8Se38.2). Te61.8Se38.2thin films were prepared by thermal evaporating system under pressure about (5×10-5) mbar. Three thin films samples were prepared in one evaporation run, one in the center of the evaporation source and the other two beside it (using flat substrate holder) to study...
The resistance and Hall effect are investigated in p-Bi2Te3 and Bi2Te3〈Sn〉 with tin content x = 0.1 and 0.25 at% and hole concentrations p = (2 to 4) × 1018 cm−-3 in the temperature range 0.5 K ≦ T ≦ 300 K, at stationary magnetic fields 0 ≦ B ≦ 22 T and under hydrostatic pressure 0 ≦ P ≦ 5.3 × 108 Pa. In the samples containing Sn the oscillations o...
