Facile Synthesis and Characterization of Pentanary Zn(Co, Cd, S)Se Semiconductor Thin Films

This work, reports the synthesis of Zn1−x−yCoxCdySzSe1−z thin films by a vacuum-free, low temperature, inexpensive, easiest modified chemical route. The wettability studies indicated the hydrophobic nature of as-grown samples. The energy dispersive spectroscopic analysis revealed the addition of Co, Cd, and S in the ZnSe host. Further, the chemical analysis confirmed the oxidations states of constituents as Zn2+, Co2+, Cd2+, S2− and Se2−. The Fourier transform spectroscopy was used to identify the existing bond structure in the films. The morphology of the as-grown thin films showed a distribution of globular grains over the surface of elongated multi-faceted crystallites.
