Angle-Resolved Pl Spectra of WS2 Monolayer on Different Substrates at Room Temperature

Caption

a-f, Angle-resolved PL spectra of WS2 monolayer on three different substrates with σ+ (σ-) detection along Γ-X direction. a and b correspond to WS2 monolayer on a flat substrate. c and d correspond to WS2 monolayer on the PhC slab with in-plane inversion symmetry. e and f correspond to WS2 monolayer on the PhC slab without in-plane inversion symmetry. g-h, Separation of σ+ (red) and σ- (blue) polarized light at 615 nm (dot line) and 628 nm (solid line) in e-f.
