Flat-band mechanism for strongly bound dark excitons in two-dimensional magnetic semiconductors
Abstract Two-dimensional (2D) materials provide an essential platform for the formation and manipulation of excitons, in which 2D magnetic materials often host weakly dispersive flat bands arising from localized d orbitals. Using CrSBr and CoCl₂, we show that such flat bands support dark Frenkel exc...
