| Abstract | ||
| This work includes a study of the effect of Ag doping in CdSe on optical, structural and Electrical properties, through changing the ratio of the added Ag with (0, 1, 5, 10) % to the final prepared CdSe solution. Measurements of the transmittance, absorption of the prepared samples of CdSe for wave lengths in the band (400nm-750nm) is carried out. It is found that the band gap decreased (Eg=(1.97,1.92,168,152)eV) respectively as Ag concentration increased. X-ray diffraction (XRD) measurements shows that the deposited pure CdSe thin film is polycrystalline with hexagonal structure, whereas doped films with Ag shows cubic structure in the[111] direction. Electrical conductivity measurement of the films showed an increase with increasing the Ag concentration, also an increase in crystal alignment found. | ||
