Extended Data Fig. 10: Band alignment in MoSe2/WS2.
From: Tuning layer-hybridized moiré excitons by the quantum-confined Stark effect
a,b, Doping-dependent reflectance contrast spectrum of a 20° aligned MoSe2/WS2 bilayer focusing on the fundamental intralyer exciton in MoSe2 (a) and WS2 (b). The horizontal dashed lines mark the onset of electron and hole doping. The intralyer exciton in MoSe2 loses oscillator strength and evolves into the red-shifted feature (charged excitons) upon both electron and hole doping, suggesting a type I band alignment.
