a Scheme of the exciton energy between the two materials. b Experimental values of the PL integrated intensity as a function of the tip position for the two materials. The bright and dark contributions in WSe2 have been added and PL integrated intensities have been normalized away from the junction. c Modeling results of the spatially integrated PL intensity assuming a perfect collection of all photons. Inset: results without considering an energy difference at the junction. d Modeling results of the PL intensity at the maximum of the PL profile.
