Exact multivalley envelope function theory of valley splitting in Si/SiGe nanostructures (opens in new tab)

Author(s): Lasse Ermoneit, Abel Thayil, Thomas Koprucki, and Markus KantnerValley splitting in strained Si/SiGe quantum wells is a central parameter for silicon spin qubits and is commonly described with envelope function and effective mass theories. These models provide a computationally efficient continuum description and agree well with atomistic approaches when the con…[Phys. Rev. B 113, 245306] Published Thu Jun 18, 2026
