Electronic states in superlattices: A new theoretical approach within the memory function formalism

A new approach is proposed for studying the electronic structure of superlattices. The novelty consists in our efficiently combining standard k-space and memory function methods for describing the electron motion perpendicular and parallel to the superlattice axis, respectively. Our approach is comp...

Zusammenfassung:A new approach is proposed for studying the electronic structure of superlattices. The novelty consists in our efficiently combining standard k-space and memory function methods for describing the electron motion perpendicular and parallel to the superlattice axis, respectively. Our approach is computationally manageable and can account for charge transfer at the layer interfaces.
