Quasiparticle effect on electron confinement in Si∕SiO2 quantum-well structures

K. Seino, J.‐M. Wagner, F. Bechstedt

Open publisher page 15 citations

Abstract

Based on ab initio density functional theory the influence of many-body excitation effects on band structures of Si∕SiO2 multilayers with nanometer thickness is studied. The quasiparticle band structures are calculated within the GW approximation to the exchange-correlation self-energy. The resulting fundamental energy gaps are discussed and compared with experimental data.
