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…

Variability of hole spin qubits in planar Germanium
Biel Martinez, Yann-Michel Niquet
Hole spin qubits in Ge/GeSi heterostructures benefit from the clean environment of epitaxial interfaces and from the intrinsic spin-orbit coupling that enables efficient electrical…
