چکیده انگلیسی
CdSexTe1âx (0 â¤Â x â¤Â 1) compound has been prepared by direct reaction of elemental cadmium, selenium and tellurium and thin films of CdSexTe1âx have been deposited onto well-cleaned glass substrates by hot wall deposition technique. CdSexTe1âx thin films have been deposited using a hot wall arrangement consisting of a quartz tube of 6.5 cm length and 1 cm diameter. The composition of the deposited films has been identified using energy dispersive analysis of X-rays. X-ray diffraction studies revealed that the prepared CdSexTe1âx bulk and deposited thin films are polycrystalline in nature with cubic zinc blende or hexagonal structure or both depending on the composition. CdSexTe1âx was found to exhibit a structural phase transition as a function of composition. The micro-structural parameters such as grain size, dislocation density and strain have been evaluated and their thickness dependence has been analysed. Photoluminescence spectra of the deposited films have been studied.
