Abstract

Semiconducting n-type cadmium indium selenide (CdInSe) thin films have been deposited on glass substrate using chemical bath technique at temperatures 313 k, 333 K and 353 K respectively, due to their tailored properties than the individual elements find potential applications in optoelectronic devices. Studies on the structural properties of the films were carried out by X-ray diffraction and scanning electron microscopy techniques revealed the cubic structure and the surface morphology. The presence of elemental constituents was confirmed using energy dispersive X-ray analysis. From the transmittance spectra it was found that the transition was direct with band gap energy ranging between 2.28 eV-1.55 eV.
