conduction band potential obtained from the threshold measurements shows only a small deviation from a fiat band, less than โข i 0.05 eV, tip to a point 4 A, from the silicon surface. There is no indication of a large ionic charge or of a greatly reduced SiO, bandgap to within about two lattice units
