Abstract

Applying Cu-deficiency and In-alloying simultaneously in CuGaTe₂ can adjust distortion parameters to be around unity, resulting in cubic-like degenerate band-edge electronic state and thus greatly enhanced electrical performance. Combined with reduced thermal conductivity, considerable TE performance has been achieved in pseudocubic CuGaTe₂-based compounds.
