Sharp periodic Ge concentration modulations beyond the conduction band valley wavevector $k_{0}$ in nuclear spin-free Si quantum wells

Ivo Rahlff, Carsten Richter, Martin Schmidbauer +13

Periodic Ge modulations within strained Si quantum wells in SiGe heterostructures offer a route to deterministically enhance conduction-band valley splitting in Si, a key requireme…

Valley physics in the two bands $k \cdot p$ model for SiGe heterostructures and spin qubits

Tancredi Salamone, Biel Martinez Diaz, Jing Li +2

We discuss the choice and implementation of inter-valley potentials in the so-called two bands $k \cdot p$ model for the opposite $X$ , $Y$ or $Z$ valleys of silicon…

Valley Splittings in Si/SiGe Heterostructures from First Principles

Lukas Cvitkovich, Tancredi Salamone, Christoph Wilhelmer +3

We compute valley splittings in Si/SiGe superlattices using ab initio density functional theory (DFT). This first-principle approach is expected to provide an excellent description…

Interface probe for antiferromagnets using geometric curvature

Tancredi Salamone, Magnus SkjÃ¦rpe, Henning G. Hugdal +2

We propose that geometric curvature and torsion may be used to probe the quality of an uncompensated antiferromagnetic interface, using the proximity effect. We study a helix of an…
