Negative terahertz conductivity at vertical carrier injection in a black-Arsenic-Phosphorus-Graphene heterostructure integrated with a light-emitting diode

Victor Ryzhii, Maxim Ryzhii, Taiichi Otsuji +4

We propose and analyze the heterostructure comprising a black-arsenic-phosphorus layer (b-As${}_{1-x}$P${}_x$L) and a graphene layer (GL) integrated with a light-emitting diode (LED).…
