At low injection energies, we find electrons in the beam scatter by small-angles, as has been previously observed. At high injection energies, we find a surprising result: placing the SGM tip where it back-scatters electrons increases the differential conductance through the system. This effect is explained by a non-equilibrium distribution of electrons in a localized region of 2D","authors_text":"D. Goldhaber-Gordon, K. W. West, L. N. Pfeiffer, M. A. Topinka, M. Grobis, M. P.
