valley splitting in thin silicon films from a two band k p model
Abstract
The unprimed valley structure in (001) silicon thin films has been analyzed within the two-band k·p model. It is shown that the two-fold degeneracy of the unprimed subbands can be lifted leading to the socalled valley splitting which is proportional to the strength of the perpendicular magnetic field. The valley splitting can be enhanced in 〈110〉 oriented point contacts, while it is suppressed in a 〈100〉 point contact. Finally, the valley splitting can be controlled and made larger than the Zeeman splitting by shear strain.This makes silicon very attractive for spintronic applications.
