Thermoelectric material

Composite crystals were prepared by including Cd-As arsenides into CdSnAs₂ as secondary phases. As a result of the evaluation of various thermoelectric properties, ZT was confirmed to be approximately 42% higher than that of the sample with stoichiometric composition in the Cd₃As₂-containing sample.
