One complication in this method is the need for computation of the "self-energy" functions that account for the interactions between the active portion of a device and its leads. In the one-dimensional case, these functions may be computed analytically. In higher dimensions, a numerical approach is required. In this work, we generalize earlier methods that were developed for tight-binding Hamiltonians, and present results for the case of a carbon nanotube %Z nonequilibrium Green's function calculations;semiinfinite carbon nanotubes;nanoscale electronic devices;selfenergy functions;tight-binding Hamiltonians;C; %9 article
