Fig. 5. Magnetic field effect on interlayer excitons.
a, PL spectra for applied magnetic fields between +3 T and -3 T for left- and right-circularly polarized (CP) emission for IX1 (left column) and IX2 (right column). b, energy shift ΔE between right- and left-CP peaks for IX1 and IX2. Error bars are calculated from the statistical error on the fitting procedure used to determine the peak position.
