Abstract
:
The object of this article was to study the crystal structure of Indium Arsenide (InAs) in both powder and thin films form , using x-ray diffractometry.The x-ray diffraction patterns of powder InAs showed polycrystalline structure of cubic phase with lattice constant of: a = 6.0524 ?The x-ray diffraction patterns of InAs thin films showed the crystal structure of cubic system and preferential orientation (111) plane and the annealing effect is increase of the degree of crystallininty. The transport of electrical properties such as electrical resistivity ? was studied for films of different thickness as deposited. It was found that for InAs films the electrical conductivity is strongly affected by the sample temperature , the heat treatment and film thickness. InAs films showed semiconducting behavior. The dependence of electrical resistivity on film thicknesses showed that the electrical resistivity increases as the film thicknesses increases. The activation energy ?E1 , ?E2 of the free charge carriers for InAs samples was calculated using the electrical resistivity data at different temperatures for different thicknesses was found that the activation energy decreases as the film thicknesses increases.
