(a) The oscillatory magnetoresistance and the transverse magnetoresistance of the 2DEG as a function of the applied magnetic field perpendicular to the heterointerface at . The inset shows a schematic illustration of the layer sequence of the sample. (b) The magnetoresistance (0) as a function of the magnetic field in the low magnetic field range at different temperatures. The vertical dash line at is merely a guide for the eye.
(a) Quantum conductivity correction curves in units of as a function of the transport field at different temperatures (solid symbols). Solid lines represent the fit by a model in Ref. 14. (b) Temperature dependence of the inelastic scattering rate extracted from the fits of the WAL cures (solid symbols). The solid line shows the linear dependence of on temperature at .
Quantum conductivity correction curves in units of as a function of the transport field at different electron concentrations at the temperature of (solid symbols). The curves are vertically shifted for clarity. Solid lines represent the fit by a model in Ref. 14.
Dependence of the Rashba SO coupling constant (solid symbols) and the SO scattering time (open symbols) extracted from the fits of the WAL cures on the electron concentration of the 2DEG. The lines are merely guides for the eye.
