Zero-bias spin separation
Sergey D. Ganichev, Vasily V. Bel'kov, Sergey A. Tarasenko +12
Spin-orbit coupling provides a versatile tool to generate and to manipulate the spin degree of freedom in low-dimensional semiconductor structures. The spin Hall effect, where an e…
Highly efficient room temperature spin injection in a metal-insulator-semiconductor light emitting diode
P. Van Dorpe, V. F. Motsnyi, M. Nijboer +6
We demonstrate highly efficient spin injection at low and room temperature in an AlGaAs/GaAs semiconductor heterostructure from a CoFe/AlOx tunnel spin injector. We use a double-st…
Electrical Spin Injection in a Ferromagnetic / Tunnel Barrier/ Semiconductor Heterostructure
V. F. Motsnyi, V. I. Safarov, J. De Boeck +4
We demonstrate experimentally the electrical ballistic electron spin injection from a ferromagnetic metal / tunnel barrier contact into a semiconductor III-V heterostructure. We in…
Skipping orbits and enhanced resistivity in large-diameter InAs/GaSb antidot lattices
J. Eroms, M. Zitzlsperger, D. Weiss +6
We investigated the magnetotransport properties of high-mobility InAs/GaSb antidot lattices. In addition to the usual commensurability features at low magnetic field we found a bro…
