Abstract
In this talk, we will present our general multiband k. p approach to describe the properties of spin-polarized transport and spin-dependent tunneling within semiconductors interfaces and related heterostructures. Hereafter, we will apply our formalism and platform to describe the properties of spin-dependent tunneling along the particular [110]-direction. This represents a nontrivial case for the description of the spin-current because of the presence of order terms in the wave vector k higher than two in the effective Hamiltonian. We demonstrate here that the multiband techniques employed and developed here beyond the actual state of the art also appear to be a perfect numerical tool to check and validate some analytical developments e.g. based on perturbation technique approaches, also allowing to alleviate some fundamental analytical issues.
