Gisi B^{1, †,}, Sakiroglu S², Sokmen İ²

Dispersion relations of the lowest subbands. (a) Variation of the energies for weak Rashba SO couplingΔ_R= 0.05 and magnetic fieldB= 5 T described with an angleθ=π/2. Solid line presentsΔ_D= 0.01, dashed line corresponds toΔ_D= 0.1, and the dotted line stands forΔ_D= 0.3. (b) Dependence of the first spin-split subband on the orientation of external magnetic field for strong SO regime characterized byΔ_R= 0.2 andΔ_D= 0.1. Solid line corresponds toθ= 0, the dashed line presentsθ=π/4, and the dotted line isθ=π/2.
