Considering the Kronig-Penney (KP) model we propose a new type of δ-function transformation which replaces rectangular potentials by δ-walls (or δ-wells). This approach leads to an energy-dependent δ-potential strength in contrast with the original KP calculations, where this quantity was ...
Kronig-Penney modelGreen functiondensity-of-stateselectronic structureA Green function formalism for density-of-states calculations is applied to investigate the electronic structure of a semi-infinite superlattice in contact with a substrate. Density-of-states and space-charge distributions are computed ...
