A curved two-dimensional electron gas with spin–orbit interactions due to the radial confinement asymmetry is considered. At a certain relation between the spin–orbit coupling strength and curvature radius the tangential component of the electron spin becomes a conserved quantity for any spin-independent scattering potential that leads to a number of interesting effects such as persistent spin helix and strong anisotropy of spin relaxation times. The effect proposed can be utilized in non-ballistic spin-field-effect transistors.
