Enhanced longevity of the spin helix in low-symmetry quantum wells
Daisuke Iizasa, Makoto Kohda, Ulrich Zülicke +2
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 ind…
Persistent spin textures and currents in wurtzite nanowire-based quantum structures
Michael Kammermeier, Adrian Seith, Paul Wenk +1
We explore the spin and charge properties of electrons in wurtzite semiconductor nanowires where radial and axial confinement leads to tubular or ring-shaped quantum structures. Ac…
In-plane magnetoelectric response in bilayer graphene
Michael Kammermeier, Paul Wenk, Ulrich Zülicke
A graphene bilayer shows an unusual magnetoelectric response whose magnitude is controlled by the valley-isospin density, making it possible to link magnetoelectric behavior to val…
Ultralong spin lifetimes in one-dimensional semiconductor nanowires
Florian Dirnberger, Michael Kammermeier, Jan König +9
We experimentally demonstrate ultralong spin lifetimes of electrons in the one-dimensional (1D) quantum limit of semiconductor nanowires. Optically probing single wires of differen…
Spin relaxation in wurtzite nanowires
Michael Kammermeier, Paul Wenk, Florian Dirnberger +2
We theoretically investigate the D'yakonov-Perel' spin relaxation properties in diffusive wurtzite semiconductor nanowires and their impact on the quantum correction to the conduct…
Magnetoconductance correction in zinc-blende semiconductor nanowires with spin-orbit coupling
Michael Kammermeier, Paul Wenk, John Schliemann +3
We study the effects of spin-orbit coupling on the magnetoconductivity in diffusive cylindrical semiconductor nanowires. Following up on our former study on tubular semiconductor n…
