Formation of dark excitons in monolayer transition metal dichalcogenides by a vortex beam: optical selection rules

Omadillo Abdurazakov, Chunqiang Li, Yun-Pil Shim

Monolayer transition metal dichalcogenides host tightly-bound excitons, which dominate their optoelectronic response even at room temperatures. Light beams are often used to study…
