Graphene as a Tunable Nonradiative Bath for Moiré Excitons

A minimal theory of nonradiative energy transfer from a two-dimensional (2D) moiré exciton to a nearby graphene layer is presented. From Fermi’s golden rule the transfer rate is the overlap of the exciton near-field spectrum with the dissipative density response of graphene, weig...
