Quasi-particle band structures and optical properties of the "magic sequence" SiGe superstructure

Mohammad Reza Ahmadpour Monazam, Kurt Hingerl, Peter Puschnig

The quasi-particle band structure and dielectric function for the so-called magic sequence SiGe${}_2$Si${}_2$Ge${}_2$SiGe${}_{12}$ (or ${\alpha }_{12}$) structure [PRL 108, 027401 (2012)] are calc…
