    Abstract

    CuFeS2 is an earth-abundant material with a potential for use in thermoelectric power generation. It is an n-type semiconductor with a small band gap, a large thermopower, and a low electrical resistivity. Previous studies have focused on the electrical properties and doping the material, to some success. In this study, we investigate the effects of selenium substitution on the sulfur site in an attempt to lower thermal conductivity while maintaining good electrical properties. Our results shows that selenium substitution is an effective method of improving zT through a large increase in power factor, and works well for reducing thermal conductivity at room temperature, but is not as effective in this regard at higher temperatures.
