Silicene spintronics — A concise review |
Quantum spin and valley Hall conductivities as functions of the perpendicular electric field for a fixed value of the SOI (3.9 meV). Blue and green: quantum spin Hall conductivities for the Fermi level in the band gap and the conduction band, respectively. Red and magenta: valley Hall conductivities for the Fermi level in the band gap and the conduction band, respectively. Reproduced with permission from Ref. [ 41 ]. Copyright 2013 AIP Publishing LLC. |
