The structure of Ge 5As xSe 95-x (x=10, 20, 30, 38at.%) and Ge 15As xSe 85-x (x=10, 25, 34at.%) glasses has been investigated by high-energy x-ray diffraction and extended x-ray absorption fine structure measurements. The experimental datasets have been modelled using the reverse Monte Carlo simulation technique. The model atomic configurations have been analysed in detail. It has been found that the homonuclear Ge-Ge, As-As, Se-Se and heteronuclear Ge-As bonds play an important role in the...[Show more]
