Gate-dependent reflection contrast spectrum for a WSe2 monolayer (a) and WSe2/graphene heterobilayer (b) encapsulated by hBN and gated with few-layer graphite. White dashed lines in (a) mark the onset of electron and hole doping in WSe2. b, shows the same data as Fig. 2a in a larger energy range and different color scale, indicating the absence of charged excitons.
