Valence Band Structure Degeneracy Enhanced Thermoelectric Performance in β‑Cu2Se

Cu2Se is known to be a promising p-type thermoelectric material resulting from its extremely low thermal conductivity. On the other hand, compared to other high-performance thermoelectric materials like PbTe, the valence band degeneracy of Cu2Se is 4 times lower, which is believed to be unfavorable...
