Structural, Optical and Electrical Properties of CdSe Nanocrystalline Films

In this article we report the preparation of cdse thin films by chemical bath deposition method (cbd).the asdeposited film grew with nanocrystalline cubic phase. the effect of annealing temperature, annealing time, depositiontime and the temperature dependent of the dc-conductivity of cdse nanoparticle films has been studied. it isshown that the optical gap and electrical properties are function of the key parameters and the electrical conductivityin the temperature range 300-475 k is dominated by the hopping of charge carrier between localized states.
