Abstract : The electrical properties of these materials are very important to understand the transport mechanism in them. A common feature of these materials is the presence of localized states in the mobility gap due to inherent defects and long range order. Amorphous semiconductors are practically being used as optical materials in a number of cases. These have distinct advantages, viz large packing density, mass replication, fast data rate, high signal to noise ratio and high immunity of defects. The present aim to study the electrical properties of amorphous chalcogenide materials. The amorphous materials will be prepared by melt quenching technique. The amorphous thin films shall be prepared by thermal evaporation technique. The temperature dependence of the electrical conductivity () is the simplest and more informative electrical property of amorphous semiconductors. The dc conduction is very important because it provide useful information about the transport mechanism in chalcogenide glasses. The values of activation energy (Ec) and pre-exponential factor (0) have been calculated by using this equation. The activation energy alone does not provide any information as to whether the conduction takes place in the extended state above the mobility edge or by hoping in the localized state.
