Phys. Rev. B 41, 8278–8287 (1990)Zero-field spin splitting in a two-dimensional electron gasReceived 26 May 1989; published in the issue dated 15 April 1990 The spin splitting in zero magnetic field which was recently reported in InxGa1-xAs/In0.52Al0.48As heterostructures is analyzed with use of the inversion-asymmetry, or k3, term and the interface spin orbit or Rashba term. Comparison with experimental data shows that Rashba term is the dominant spin-splitting mechanism in these samples. Zero-field spin splittings of 2.5–2.75 meV are deduced from the perpendicular-field data. Analysis of tilted-magnetic-field data gives g factors that lie between -2 and -3. © 1990 The American Physical Society URL:
