(a) The electric field as a function of distance from the substrate. (b) The difference between the Fermi energy Ef and the top of valence band energy Ev as a function of distance from the substrate. For both plots, the red curve is for an applied voltage of Vg = −2.5 V, the blue curve is for Vg = 3.2 V. The buffer and film regions are indicated.
