We derive the effective dimensionally reduced Schrödinger equation with spin–orbit interaction (SOI) in low-dimensional electronic strain-driven nanostructures. By employing a method of adiabatic separation among fast normal quantum degrees of freedom and slow tangential quantum degrees of freedom, we show the emergence of a strain-induced Rashba-like SOI. By applying this analysis to one-dimensional (1D) curved quantum wires we demonstrate that the curvature-induced Rashba SOI leads to enhanced spin–orbit effects.
