a, Evolution of differential reflection (DR) spectra of intralayer excitons following gradual displacement from a bright to dark region (shown from top to bottom for positions indicated by the black dots in Supplementary Fig. 9a). The peak multiplicity is a hallmark of nanoscale reconstructed domains. b–d, Interlayer exciton PL (b), Pc (c) and dispersion in a perpendicular magnetic field B (d), characteristic of extended 2D domains. The magneto-luminescence data were recorded under linearly polarized excitation with σ+ detection to determine the g-factor values from linear slopes. e–g, Same as b–d but for regions of 1D stripes with a large degree of linear polarization (as shown in the inset). h–j, Same as b–d but in a dark sample region of 0D domains (PL spectra shown with offsets and different scaling for excitation powers of 100, 2 and 0.01 μW). All data were recorded on sample 2 (Supplementary Fig. 9) ; g-factor values with least-square error bars were obtained from linear fits to the data shown in Supplementary Fig. 16.
