摘要：

The EXAFS measurements on As and Te K-edges of liquid As2Te3 have been carried out in the temperature range including the supercooled liquid state down to 330 degrees C. By curve-fitting analyses with two-shell model the bond lengths and the coordination numbers were determined. It is suggested that As atoms within a chain bridge neighbouring chains with decreasing temperature and the network structure with three-fold coordinated As and two-fold coordinated Te is formed near the glass transition temperature.
