摘要: Spin splitting of subband states in semiconductor heterostructures at B=0 is ascribed to the inversion asymmetry--induced bulk ${\mathrm{k}}^{3}$ term, which dominates large-gap materials, and interface spin-orbit or Rashba becomes important narrow-gap systems. We show for AlGaAs/GaAs how this finite spin evolves from Zeeman B\ensuremath{\ne}0 predict a vanishing -magnetic- field ---, depends on electron concentration layer.
