Fig. 2: Doping-dependent reflectance contrast spectra of 3L WSe2/ 1L WS2 and natural trilayer WSe2 Devices.
From: Exciton Superposition across Moiré States in a Semiconducting Moiré Superlattice
a, b and e are the schematic atomic structure, band alignment, and the doping-dependent reflectance contrast spectra of 3L WSe2/ 1L WS2 measured from device D1. c, d and f are the schematic atomic structure, band alignment, and the doping-dependent reflectance contrast spectra of natural trilayer WSe2 measured from device D2. The blue arrow in e denotes the enhanced reflection signal of the hybridized exciton (interlayer exciton \({{{{{{\rm{IX}}}}}}}_{3{{{{{\rm{L}}}}}}}^{+}\) hybridized with intralayer exciton) at the Mott insulator state at n = 1.
