Abstract: The authors present a method of producing Cu2CdSnSe4 quaternary nanocrystals using a colloidal synthesis route that could be used for future industrial synthesis. The nanocrystals prepared showed great potential for use as a thermoelectric material due to their high thermoelectric figure of merit (up to 0.71) resulting from a high electrical conductivity and low thermal conductivity. The authors believed that these properties could be further tuned in order to increase the figure of merit by adjusting the copper to cadmium ratio.
