Abstract
Te/Cd/Zn stack was prepared using stacked elemental layer (SEL) method. XRD results showed the effect of Zn concentration on the growth of CdTe in their preferred orientations. Optical studies revealed a reduction in band gap from 1.35 to 1.42 eV as well as low transmittance for higher Zn concentration. Improved surface morphology was the evidence of effects of Zn concentration on micro structural damage and the grain growth. Significant change on particle size, grain size and porosity was attributed to the influence of Zn concentration presented in the stack. ImageJ software also used to identify the presence of nano size particles in the annealed stack. EDAX studies revealed the presence of desired compositions in the annealed stacks.
