Abstract :
We have observed the weak antilocalization (WAL) and beating SdH oscillation through magnetotransport measurements performed on a heavily δ -doped In0.52Al0.48As/In0.53Ga0.47As/In0.52Al0.48As single quantum well in an applied magnetic field up to 13 T and a temperature at 1.5 K. Both effects are caused by the strong Rashba spin–orbit (SO) coupling due to high structure inversion asymmetry (SIA). The Rashba SO coupling constant α and zerofield spin splitting Δ 0 are estimated and the obtained values are consistent from different analysis for this sample.
