Extended Data Fig. 1: Doping-dependent reflectance contrast in WSe2/WS2 bilayers.
From: Tuning layer-hybridized moiré excitons by the quantum-confined Stark effect
Results are from WSe2/WS2 bilayers with a twist angle close to 20° (a,b), 60° (c,d), and 0° (e,f). Upper and lower panels show the energy windows corresponding to the fundamental exciton resonances in WS2 and WSe2, respectively. The horizontal dashed lines denote the filling factors of the moiré superlattice (v > 0 for electron filling and v < 0 for hole filling).
