شبیه سازی اثر بی نظمی و میدان مغناطیسی بر ترابرد کوانتومی نانوساختارهای دو بعدی مدل شده با تقریب تنگابست
In recent years, semiconductor nanostructures have become the model systems of choice for investigation of electrical conduction on short length scales. Quantum transport is studied in a two dimensional electron gas because of the combination of a large Fermi wavelength and large mean free path. In the present work, a numerical method is implemented in order to contribute to the understanding ...
متن کاملMesoscopic spin Hall effect in multiprobe ballistic spin-orbit-coupled semiconductor bridges
We predict that unpolarized charge current driven through the longitudinal leads attached to ballistic quantum-coherent two-dimensional electron gas 2DEG in semiconductor heterostructure will induce a pure spin current, which is not accompanied by any net charge flow, in the transverse voltage probes. Its magnitude can be tuned by the Rashba spin-orbit SO coupling and, moreover, it is resilient...
متن کاملSpin-Orbit Based Coherent Spin Ratchets
The concept of ratchets, driven asymmetric periodic structures giving rise to directed particle flow, has recently been generalized to a quantum ratchet mechanism for spin currents mediated through spin-orbit interaction. Here we consider such systems in the coherent mesoscopic regime and generalize the proposal of a minimal spin ratchet model based on a non-interacting clean quantum wire with ...
متن کاملMesoscopic Spin Hall Effect in Multiprobe Semiconductor Bridges
We predict that pure spin current flowing through the transverse leads of quantumcoherent two-dimensional electron gas (2DEG), which is induced by conventional unpolarized charge current driven through the longitudinal leads, can be tuned by the Rashba spin-orbit (SO) interaction and will decay only when disorder is sufficiently strong (but before electrons become localized). Furthermore, the p...
