Rattling “guest” impurities in Si and Ge clathrate semiconductors

In addition to their ground state, diamond structure, Si, Ge and Sn can form crystalline solids called clathrates. As in the diamond structure, in the clathrates, the Group IV atoms are tetrahedrally coordinated and sp 3 covalently bonded to their neighbors. However, the clathrates contain pentagona...
