Modelling the electron and hole states in semiconductor
... field and mechanical strain are modelled in the k · p theory. When applied to nanostructures, the multiband k · p theory could give rise to spurious solutions, which are an artifact due to an incomplete description of the electronic structure by the k · p theory. In practice, spurious solutions are ...
