Abstract

The values of the zero-field spin-splitting energy Δ0 in InAlAs/InGaAs/InAlAs heterostructures are investigated using anti-weak-localization analysis. The obtained values for Δ0 are compared with values that were theoretically predicted assuming Rashba spin-orbit coupling (denoted by ΔR). The good agreement between Δ0 and ΔR and their dependence on quantum well asymmetry suggest that our approach provides a useful tool for designing future spintronics devices using Rashba spin-orbit coupling.
