Dresselhaus-like spin splitting in (hkl) InAs/GaSb superlattices

摘要

For the no-common-atom superlattices, the new phenomenon of zero-field spin splitting is predicted by the modified bond orbital model. Apart from the (001)- and (111)-oriented superlattices, this spin splitting appears along the growth directions of superlattices. Moreover, it originates from the existence of heterobonds inside the interfacial unit cells. This phenomenon due to the microscopic symmetry reduction is similar to the concept of the Dresselhaus effect and thus termed as the Dresselhaus-like spin splitting.
