Mixed anion layered compounds LaCuChO (Ch = S, Se) is a wide-gap semiconductor with optical band gap ~ 3 eV. In LaCuChO (Ch = S, Se) compouds, ~ 1 at.% Cu defects in crystallographic sites generate p-type carriers. In the meeting, I will demonstrate the thermoelectric transport properties of LaCuChO (Ch = S, Se) using Jonker plot.
