Abstract

A new stannite phase was synthesized and its temperature dependent transport properties were investigated. It is found that the electrical resistivity increases with increasing temperature. Hall and Seebeck coefficient measurements indicate Cu2CdSnTe4 possesses p-type conduction, as is the case for other stannite compositions. The temperature dependence of the thermal conductivity, κ, exhibits typical dielectric behavior, however the κ values for Cu2CdSnTe4 are higher than those of the selenium containing stannite materials. Electronic structure calculations are used to describe the transport characteristics and the potential for thermoelectric applications is also discussed.
