Full-band quantum transport simulation in presence of hole-phonon interactions using a mode-space k·p approach

Fabrication techniques at the nanometer scale offer potential opportunities to access single dopant features in nanoscale transistors. Here we report full-band quantum transport simulations with hole-phonon interactions through a device consisting of two gates- all-around in series and a p-type Si nanowire channel with a single-dopant within each gated region. For this purpose, we have developed and implemented a mode-space based full-band quantum transport simulator with phonon scattering using the six-band k.p method. Based on the non-equilibrium Green's function formalism and the self-consistent Born's approximation, an expression for the hole-phonon interactions self-energy within the mode-space representation is introduced.
