9 Jan 2007 | | Journal: | Phys. Rev. B 73, 35313 (2006) | | Subject: | Mesoscopic Systems and Quantum Hall Effect; Materials Science | | Abstract: | Electrons with spin-orbit coupling moving in mesoscopic structures can often exhibit local spin polarization. In this paper, we study the influence of the Rashba coupling on the scattering of two-dimensional electrons from a circular disk. It is observed that spin-polarized regions exist, even if the incident electrons are unpolarized. In addition to the distributions of charge and spin current in the near-field region, we also analyze the symmetry and the differential cross-section of the scattering. | | Source: | arXiv, cond-mat/0701162 | | Services: | Forum | Review | PDF | Favorites | |
