Abstract
Thermal evaporation technique was used to prepare Cu13Se52Bi35 thin films. The asdeposited and annealed samples were investigated by using the X-ray diffraction (XRD), scanning electron microscopy (SEM) and optical transmission and reflection. The XRD showed that the as-deposited film is crystalline in nature, and the crystalline size of samples increased with increasing the annealing temperature. SEM images showed that the morphology of the sample changes with the annealing temperature. The direct transition of the optical band gap (Eg) of Cu13Se52Bi35 films was observed and the values of Eg decreased with increasing the annealing temperature. Other optical parameters were also investigated.
期刊介绍:
Chalcogenide Letters (CHL) has the aim to publish rapidly papers in chalcogenide field of research and
appears with twelve issues per year. The journal is open to letters, short communications and breakings news
inserted as Short Notes, in the field of chalcogenide materials either amorphous or crystalline. Short papers in
structure, properties and applications, as well as those covering special properties in nano-structured
chalcogenides are admitted.
