    • C, but for the present case the dominant contribution to the integral of Eq. (C3) arises from energy values that are in the lower portion of the band gap so that our use of the light-hole mass of the Ge VB is a good approximation.

    • This spreading is most easily understood within a planar tunneling model where it is a direct consequence of satisfying both energy and parallel wave vector conservation [analogous to that occurring in ballistic-electron-emission microscopy, see L. D. Bell and W. J. Kaiser, Phys. Rev. Lett. 61, 2368 (1988)], but will also occur for the more spherical geometry of a sharp probe tip.
