چکیده انگلیسی
Polycrystalline quaternary chalcogenides with compositions Cu1.1Cd1.8In1.1Te4, Cu1.3Cd1.9In0.8Te4, Cu1.2Zn1.8InTe4 and Cu1.2Zn1.6In1.2Te4 were synthesized by reacting the constituent elements and subsequent solid state annealing followed by densification by hot-pressing in order to investigate the transport properties with varying compositions, and therefore carrier densities. The thermal conductivity of these compositions, as well as stoichiometric CuZn2InTe4 and CuCd2InTe4, are reported for the first time. In addition to the thermal conductivity, resistivity, Seebeck coefficient and compositional stability measurements are also discussed. These materials are p-type semiconductors with very low thermal conductivity values. The potential for improved thermoelectric performance is also discussed.
