Fig. 5: Tunable effective g-factors.
a Evolution of the energy bands (CB, HH, and LH) as a function of the SL period (tperiod = tInAsSb + tInSb = 1.6tInAsSb), calculated using the band parameters extracted from the experiment. b Evolution of the effective g-factors for the CB, extracted using two different methods, as a function of tInAsSb. The error bars are determined by varying the Kane energy Ep, as explained in the Supplementary Note 5. Red circles label out the three SL samples measured in this work, where tInAsSb = 3 nm, 4 nm, and 5 nm, respectively. Inset: The extracted Fermi velocity vF from the four-band model as a function of tInAsSb. c The CB component in the wavefunction as a function of tInAsSb. The calculation is performed at 1 T. Insets: Band evolution from the normal state to the inverted state as increasing the SL period. The critical state is indicated by a vertical dash line.
