Spin Hall effect in a two-dimensional electron gas in the presence of a magnetic field
P. Lucignano, R. Raimondi, A. Tagliacozzo
We study the spin Hall effect of a two-dimensional electron gas in the presence of a magnetic field and both the Rashba and Dresselhaus spin-orbit interactions. We show that the va…
Rashba quantum wire: exact solution and ballistic transport
C. A. Perroni, D. Bercioux, V. M. Ramaglia +1
The effect of Rashba spin-orbit interaction in quantum wires with hard-wall boundaries is discussed. The exact wave function and eigenvalue equation are worked out pointing out the…
Spin polarization of electrons with Rashba double-refraction
V. Marigliano Ramaglia, D. Bercioux, V. Cataudella +2
We demonstrate how the Rashba spin-orbit coupling in semiconductor heterostructures can produce and control a spin-polarized current without ferromagnetic leads. Key idea is to use…
Rashba effect induced localization in quantum networks
Dario Bercioux, Michele Governale, Vittorio Cataudella +1
We study a quantum network extending in one-dimension (chain of square loops connected at one vertex) made up of quantum wires with Rashba spin-orbit coupling. We show that the Ras…
