Stacking angle-tunable photoluminescence from interlayer exciton states in twisted bilayer graphene
Interlayer electronic states in twisted bilayer graphene are characterized by flat-band regions hosting many-body electronic effects. Here, the authors observe two-photon photoluminescence excitation and excited-state absorption spectra on graphene containing a variety of twist angles to access the...
