Multi-band Wigner Function Formulation of Quantum Transport
arXiv:cond-mat/0407218 · doi:10.1016/j.physleta.2004.05.022
Abstract
A Wigner function representation of multi-band quantum transport theory is developed in this paper. The equations are derived using non-equilibrium Green's function formulation with the generalized Kadanoff-Baym ansatz and the multi-band Hamiltonian including spin. The results are applied to a two-band resonant inter-band tunneling structure.
