Fig. 4: IX–IX exchange interaction for R- and H-type heterostructures.
From: Temperature dependent moiré trapping of interlayer excitons in MoSe2-WSe2 heterostructures
a Depiction of R-type decay channel where the IX–IX exchange interaction can scatter bright intravalley singlet IXs to dark intervalley triplet IXs. b Depiction of H-type decay channel where the IX–IX exchange interaction can scatter dark intervalley singlet IXs to bright intravalley triplet IXs.
