(color online) (a) The PL spectrum of WSe₂ bilayer measured at different temperature. (b) Temperature dependence of the direct and indirect PL emission peak energy in WSe₂ bilayer. (c) Right (σ⁺) and left (σ⁻) circularly-polarized components of circular-polarization resolved PL spectra under σ⁺-polarized laser excitation (left axis), and the polarization degree of circularly polarized PL of WSe₂ bilayer (right axis).
