Spectro-structural characterisation of CdSe1−xTex alloyed thin films

This paper presents information pertaining to the chemo-synthesis of Cd(Se, Te) thin films of variable composition which has been brought about with the objectives to study the deposition history, growth kinetics and the structural and optical changes caused due to the addition of Te in CdSe. The effects due to various process parameters such as deposition time, temperature, concentration of the basic species, speed of the substrate rotation, pH, etc. on the growth and quality of the films are studied experimentally. The films are crystalline in nature over whole range of the composition parameter with a homogeneous predominant wurtzite structure for 0≤x≤0.08 and 0.7≤x≤1 regions. For the middle range (0.15
