Principle of MIR luminescence in BP-TMDC heterostructure (IMAGE)
Caption
a, Schematic diagram of the BP-WSe2 heterostructure. Under the excitation of light, the electron and hole pairs in WSe2 can be efficiently transmitted to BP, thereby enhancing its MIR photoluminescence. b, Schematic diagram of the BP-MoS2 heterojunction diode. Under a positive bias voltage between BP and MoS2, the electrons on the conduction band of MoS2 can overcome the barrier, enter into the conduction band of BP, and recombine with abundant holes in BP. Thereby electroluminescence is achieved
