Abstract

Neutron diffraction studies were performed on $Ge_xSe_{1-x}$ glasses for x=0.1, 0.2, 0.33 and 0.4. The structure factor S(Q) shows maximum intermediate-range order for x=0.33. Analysis of the two main peaks in T(r) shows that these glasses have $Ge(Se_{1/2})_4$ tetrahedra. Glasses with $x\leq;0.2$ consist of Se-chains cross-linked with Ge-tetrahedra while for $x\geq;0.2$ Ge-tetrahedra are present in both edge- and corner-shared configurations.
