AbstractCopper selenides have recently attracted the attention of the thermoelectric community due to their high figure of merit at high temperatures (ZT¿1.6 @ 1000 K), and the existence of a crystallographic phase transition at T ¿400K at which ZT can reach values as high as 2.3. The materials have been usually prepared by solid state reaction methods, taking about a week to produce a singe sample. In this work we show a reactive sputtering method that allows the production of samples in times of some minutes, with well controlled stoichiometry and high crystallinity.
