Disorder-Induced Degradation of Vertical Carrier Transport in Strain-Balanced Antimony-Based Superlattices

We investigate carrier transport in gallium-free strained-balanced \mathrm{In}\mathrm{As}/{\mathrm{In}}_{x}{\mathrm{As}}_{1\ensuremath{-}x}\mathrm{Sb}type-II superlattices in the presence of positional and compositional disorder. We use a rigorous nonequilibrium Green's function model based on fully nonlocal scattering self-energies computed in the self-consistent Born approximation and a multiband description of the electronic structure....
