Fe-mediated phase evolution and defect regulation in flexible Cu2Se films for enhanced thermoelectric transport

The monoclinic copper selenide (α-Cu2Se) is a promising thermoelectric (TE) material due to its ordered Cu sublattice and intrinsically low thermal conductivity for near-room-temperature applications. However, excessive Cu vacancies in α-Cu2Se lead to carrier overconcentration an...
