Interstitial Cu-Induced Band Structure and Phonon Transport Regulation for Eco-friendly n-Type SnSe2 Thermoelectric Power Generation.
Layered n-type SnSe2 is a promising eco-friendly thermoelectric (TE) material, yet its practical application is constrained by low carrier concentration and the inherent coupling of electronic-thermal transport. Herein, a CuCl annealing strategy is developed to leverage Cu interstitial intercalation for the precise mod...
