Extended Data Fig. 1: Electric field dependent PL spectra for device D2.

From: Strong-interaction-driven quadrupolar-to-dipolar exciton transitions in a trilayer moiré superlattice

Extended Data Fig. 1

(a), (b), and (c) are PL spectra acquired under the CW optical excitation with the excitation intensity of 0.053 µW/µm2, 12.7 µW/µm2, and 259.1 µW/µm2, respectively. (d) Colour plot of the normalized integrated PL intensity as a function of the excitation intensity and nominal electric field. The measurements were performed at a temperature of 3.6 K.
