"dark excitons visible... measure how the excitons are formed at a time scale of a millionth of a millionth of a millisecond. We can describe the dynamics of the formation of these excitons using quantum mechanical theory developed by Professor Ermin Malic's research group at Marburg... formation of dark Moiré interlayer excitons... signature of Moiré potential imprinted on exciton... impact of combined properties... two twisted semiconductor layers"
