Pseudobinary Cd1-xPbxSe thin films

Abstract

Cd1-4PbxSe thin films with 0DEGC, in an alkaline medium (pH equals 11) and studied through the structural, optical and electrical transport properties. X- ray diffraction studies revealed that pure CdSe exists in both hexagonal and cubic phase structures whereas PbSe is only cubic. The interplanar distance, d, changed from 3.528 A0 to 3.580 A0 for the change of x from 0 to 0.2 showing the formation of an alloy in 0aSigma'S), carrier concentration (n), carrier mobility ((mu) ) and the intergrain barrier potential ((Phi) B) were estimated from the above data and their variation with the temperature and film composition have been studied.
