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 as deposited film grew with nanocrystalline cubic phase. The effect of annealing temperature, annealing time, deposi- tion time and the temperature dependent of the DC-conductivity of CdSe nanoparticle films has been studied. It is shown that the optical gap and electrical properties are function of the key parameters and the electrical conductivity in the temperature range 300-475 K is dominated by the hopping of charge carrier between localized states.
