Absorption in disordered heterostructures: Contributions from intra- and inter-subband scattering and impact of localised states

摘要

We developed a model for the exact calculation of the absorption spectrum in disordered heterostructures allowing the understanding of the lineshape in terms of the contributions from intra-subband and inter-subband scatterings. A dopant engineering of the inter-subband lineshape is proposed.
