Extended Data Fig. 1: Optical reflectance spectra in monolayer and bilayer WSe2.
From: Every-other-layer dipolar excitons in a spin-valley locked superlattice
a-b, Electric field (Ez) dependence of differential optical reflectance measurement in monolayer (a) and bilayer (b) WSe2. Doping is fixed at zero. As expected, the every-other-layer dipolar exciton as well as the anti-crossing feature are not observed.
