Enhanced longevity of the spin helix in low-symmetry quantum wells

13 Jun 2020 Iizasa Daisuke Kohda Makoto Zülicke Ulrich Nitta Junsaku Kammermeier Michael

In a semiconductor, collective excitations of spin textures usually decay rather fast due to D'yakonov-Perel' spin relaxation. The latter arises from spin-orbit coupling, which induces wave-vector-dependent spin rotations that, in conjunction with random disorder scattering, generate spin decoherence... (read more)
