Structural study of AsS(2)-Ag glasses over a wide concentration range
Original language description
(As(0.33)S(0.67))(100-x)Ag(x) (0 {= x {= 28) bulk glasses showing micro-phase separation in a wide concentration range have been studied by X-ray diffraction, neutron diffraction and extended X-ray absorption fine structure measurements. The AsAgS(2) composition, which forms a homogeneous glass, is modeled with the reverse Monte-Carlo simulation technique. It is established that Ag prefers the environment of S; Ag-As bonding cannot be observed. Similarly to the AsAgS(2) crystalline modifications smithite and trechmannite, the main structural units of the glass are AsS(3) pyramids. The covalent network of As and S atoms becomes fragmented in the glassy AsAgS(2) unlike in the glassy AsS(2). The environment of Ag atoms in the AsAgS(2) glass differs from that in the crystalline state. In average, each Ag atom has four nearest neighbors, three of them being S and one being Ag
