Abstract

Highly dense Cu_2-xS bulks, fabricated by a melt-solidification technique, show high thermoelectric performance with zT of ∼1.9 at 970 K. The Cu_2-xS bulks show good thermal heat flow and diffusivity stability, and they exhibit excellent mechanical properties, with hardness of ∼1 GPa. Density functional theory calculations indicate that Cu_2-xS is an intrinsic p-type conductor. This journal is
