Title: Synthesis, transport properties, and electronic structure of Cu{sub 2}CdSnTe{sub 4}

A new stannite phase was synthesized and its temperature dependent transport properties were investigated. Cu{sub 2}CdSnTe{sub 4} possesses strong p-type conduction, while the temperature dependence of the thermal conductivity exhibits typical dielectric behavior. Electronic structure calculations allowed for a description of the transport characteristics in terms the energy band structure, density of states, and Fermi surface. The potential for thermoelectric applications is also discussed.
