摘要

Here we report the thermoelectric properties of a wide-gap chalcopyrite compound AgInSe_2, and observed the remarkable improvement in electrical conductivity σ, due to the bandgap (E_g = 1.12 eV) reduction compared to In_2Se_3. The improvement in σ is directly responsible for the enhancement of thermoelectric figure of merit ZT, though the thermal conductivity is much higher at 500 ~ 724 K. The maximum ZT value is 0.34 at 724 K, increasing by a factor of 4, indicating that this chalcopyrite compound is of a potential thermoelectric candidate if further optimizations of chemical compositions and structure are made.
