We present the analytical result of the expectation value of spin resultingfrom an injected spin polarized electron into a semi-infinitely extended 2DEGplane with [001] growth geometry via ideal quantum point contact. Both theRashba and Dresselhaus spin-orbit couplings are taken into account. A pictorialinterpretation of the spin precession along certain transport directions isgiven. The spin precession due to the Rashba term is found to be especiallyinteresting since it behaves simply like a windshield wiper which is verydifferent from the ordinary precession while that due to the Dresselhaus termis shown to be crystallographic-direction-dependent. Some crystallographicdirections with interesting and handleable behavior of spin precession arefound and may imply certain applicability in spintronic devices.
