Extended Data Fig. 9: Periodic screening versus periodic electric potential.
From: Creation of moiré bands in a monolayer semiconductor by spatially periodic dielectric screening
a, b, The spatial dependence of the WSe2 band gap Eg (separation between the conduction band minimum CBM and the valence band maximum VBM), the 1s binding energy energy Eb(1s), and the 1s exciton energy E(1s) in (a) a periodic screening and (b) a periodic electric potential environment. The ε is the dielectric constant and V is the scalar electric potential.
