The influence of In and Ag atoms on the dc electrical conductivity and optical properties in the short wavelength edge region in Ge20Sb10S70 and Ge30Sb10S60 glasses has been examined. Contrary to the effect of In atoms, the Ag atoms at concentration levels below 4 at. % of Ag significantly influence the dc conductivity. Changes of the optical properties are less significant, and they are affected in a similar way by incorporation of In and Ag atoms into a glassy matrix. It is supposed that some of the Ag atoms are positively ionized to an Ag+ species that remains in the network. The 5s1 electron of Ag interacts with D+ states making, in the final state, an increase of D− defect states. Thus the Fermi level is shifted to the valence band and the dc conductivity increases.

Tin Oxide and Indium doped Tin Oxide (SnO2:In) thin films were deposited on glass and Silicon  substrates  by  thermal evaporation technique.  X-ray diffraction pattern of  pure SnO2 and SnO2:In thin films annealed at 650oC and the results showed  that the structure have tetragonal phase with preferred orientation in (110) plane. AFM studies showed an inhibition of grain growth with increase in indium concentration. SEM studies of pure  SnO2 and  Indium doped tin oxide (SnO2:In) ) thin films showed that the films with regular distribution of particles and they have spherical shape.  Optical properties such as  Transmission , optical band-gap have been measured and calculated.

CdHgTe thin films were grown onto glass substrate via the Chemical bath deposition technique. XRD results indicate that a CdHgTe formed with a cubic polycrystalline structure. The crystallinity of CdHgTe thin films is gradually deteriorate with increasing the gamma irradiation. EDS spectrums confirms the presence of Cd, Hg and Te elements. DC electrical conductivity results depicted the conductivity of CdHgTe increase with increasing a gamma ray dosage
