✦ Synopsis


CdSe:In films were prepared by electron beam evaporation technique using CdSe and In 2 Se 3 (purity ~99.9%) pellets. The crystal structure of the films with and without Indium, measured by X-ray diffraction (XRD), showed a typical wurtzite structure, higher Indium doping shifts the peak angle to higher side along with the broadening of the peaks. X-ray photoelectron spectroscopy (XPS) studies indicated binding energies corresponding to 54 eV (Se 3d 5/2 ), 444 eV (In 3d 5/2 ), 411 eV (Cd 3d 3/2 ), (Cd 3d 5/2 ). Atomic force microscope (AFM) studies indicated a uniform surface.The grain size decreases with increase of In doping. A decrease in the band gap was observed with increase of dopant concentration. Resistivity of the films is in the range of 10 -3 Ωcm. Carrier density was in the range of 10 21 cm -3 for the films. The photolumineasenec spectra (PL) spectra indicated three peaks. The peak intensity decreases as the Indium concentration increases.
