Abstract

Clathrates exhibit exceptional properties such as high-performance thermoelectrics. The extension of cages and guest atoms in 6d Wyckoff positions (other than 2a positions) both have huge reduction effect on the thermal conductivity of Type-I clathrates, which provides important guidance to exploring new kinds of silicon clathrates for advanced thermoelectrics.
