Harmonic sideband generation in monolayer transition metal dichalcogenides
Harmonic sidebands are compared in monolayer vs. bulk WSe2. We find strong Coulomb enhancement of sidebands in monolayer WSe2 when resonant vs. non-resonant 1s-exciton excitations are compared, this is virtually absent in bulk.
