Simultaneously boosting electrical and thermal transport properties of CuGaTe ₂ through XCl ₂ (X = Cd, Zn) doping-driven band and defect engineering

Abstract

The structure of CuGaTe 2 has been optimized by the introduction of XCl 2 (X = Cd, Zn), which creates acceptor defects and nanopores. This synergistically improves the thermoelectric and mechanical properties.
