DOI: 10.1126/sciadv.aax7407

Abstract: We report the layer-hybridized valley excitons in 2D hetero- and homobilayers manifested by band alignment and valley spin. Excitons in monolayer semiconductors have a large optical transition dipole for strong coupling with light. Interlayer excitons… read more here.
