The dark conductivity of annealed silver bromide single crystals, containing trace amounts of silver sulfide, has been measured as a function of dopant concentration. At 21 ° C the conductivity exhibited a more rapid than linear increase with silver sulfide concentration at levels below 8 ppm. At 4 ppm, the lowest level achieved, a limiting dependence of the conductivity upon the fourth pwoer o...
We employed the hybrid DFT-LCAO approach as implemented in the CRYSTAL code for 135 atom supercell calculations of O vacancies with trapped electrons (known as the F centers) in three cubic perovskite crystals: SrTiO3, PbTiO3 and PbZrO3. The local lattice relaxation, charge redistribution and defect energy levels in the optical gap are compared. We demonstrate how difference in a chemical compo...
Chalcogenide glass is an optical material with excellent mid-infrared and far-infrared penetration properties. The silver-doped Ge28Sb12Se60 (GSS) chalcogenide films in this paper were deposited on a substrate by the co-evaporation technique. A continuous laser different power outputs was then used to scan at constant speed, photobleaching (PB) effects observed using microscopy. results show th...
