Research output: Contribution to journal › Conference article › peer-review

Abstract

Authors present a simple theory of the dielectric function in superlattices. The calculation is performed separately for different symmetry points of the band structure. They assume that among the contributing states only certain states are influenced substantially by size quantization and these electronic states are calculated by using a simplified k-p method. New features of the dielectric constant of superlattices are a fine structure due to zone folding (subbands) and a small anisotropy due to the lower symmetry.
