Abstract

Single and bi-layer thin films of Cadmium Sulphide (CdS) and Zinc Selenide (ZnSe) were prepared on glass and ITO/Glass substrates by e-beam technique. Spectral transmittance of bi-layer thin film showed red shift with prolonged interference effect. The decrease in Urbach tail of bi-layer thin film signifies the decreased band gap with increased grain size. Single layer CdS film has prominent (002) hexagonal peak where as bi-layer thin film confirm with (002) hexagonal and (111) cubic peaks of CdS and ZnSe respectively. CdS grain size was found to be 14.5, 17.1, and 33.1 nm on glass, ITO/Glass and ZnSe/ITO/Glass substrates respectively.
