Extended Data Fig. 4

The gray bar indicates the intrinsic region of the device, and a detailed discussion can be found in Supplementary Section 9. White arrows suggest the filling factor of n = 1/3, 2/3, and 1, respectively. The PL spectra were taken with the CW laser excitation intensity of 3.2 µW/µm2 and temperature of 7 K.
