Single and multiband modeling of quantum electron transport through layered semiconductor devices

摘要: Non-equilibrium Green function theory is formulated to meet the three main challenges of high bias quantum device modeling: self-consistent charging, incoherent and inelastic scattering, band structure. The written in a general localized orbital basis using example zinc blende lattice. A Dyson equation treatment open system boundaries results tunneling formula with generalized Fisher-Lee form for transmission coefficient that treats injection from emitter continuum states quasi-bound on an equal footing. Scattering then included. Self-energies which include effects polar optical phonons, acoustic alloy fluctuations, interface roughness, ionized dopants are derived. Interface roughness modeled as layer cations given type cluster into islands. Two different treatments scattering; Born multiple sequential scattering formulated, described, analyzed numerical t...
