Extended Data Fig. 4: Linear-polarization-resolved photoluminescence.
From: Signatures of moiré-trapped valley excitons in MoSe2/WSe2 heterobilayers
a–c, Photoluminescence intensity plots as a function of the linear polarization detection angle and photon energy under linearly polarized excitation for θ = 57° (a), 20° (b) and 2° (c). No linear photoluminescence polarization is observed.
