Intercluster and Intracluster Interactions in Gel-xSnxSe2.

摘要

In the chalcogenide compound Germanium Selenide one can study interactions for a variety of length scales and degrees of order by comparing the glassy and crystalline forms, as the local bonding is similar in the two. When some of the Ge in the compound is replaced by Tin, the Sn atoms substitute for Ge atoms, preferentially occupying the cluster-edge sites in the glass. This study uses several techniques to examine two aspects of the ternary compounds: the location of the Sn atoms in crystalline forms of Ge(1-x)SnxSe2; and the interaction of the clusters in the glass.
