Abstract

Over 10 g of non-stoichiometric Cu(2) ZnSnSe(4) colloidal nanocrystals for thermoelectric applications are prepared after one single reaction. The obtained pellet made from the colloidal nanocrystals shows a peak ZT value of 0.44 at 450 °C, which is similar to those of state-of-the-art Cu(2) ZnSnSe(4) -based bulk materials at the same temperature.
