Spin-splitting surface states of strained GaAs(001) and spontaneous spin current from breaking of twofold symmetry
We theoretically study the electronic structure and spin splitting of a strained GaAs(001) surface with broken twofold symmetry. We introduce a surface electron Hamiltonian of our model. By k·p theory, we qualitatively evaluate the electronic structure of GaAs(001) surface, demonstrating that the sp...
