The DOS ( E ) and T ( E ) of a simple Laplace Potential. (a) Schematic of a simple Laplace potential profile with a bias of 0.3 V across the GNR channel. (b) The resulting DOS(E) versus E with red arrow indicating the new addition of DOS(E) due to the upward movement of valence band-edge by 0.3 eV. (c) T(E) versus E. Results for U = 0 and that calculated by TB-π are also included for comparison.
