Dependence of the net transferred charge on the position of the Fermi energy. N = 6 junctions are constructed along the a a-direction and b c-direction. Experimental values and error bars (standard deviation) are taken from ref. 4. Note that the results are insensitive to the position of the Fermi energy, except when μF is chosen to be close to the top of the VB (as in μF = 5.5 eV) or to the bottom of the CB (as in μF = 9.5 eV) (cf. Fig. 1b)
