7 Jun 2002 | | Journal: | Phys.Rev.B., v.67, 155310 (2003) | | Subject: | Mesoscopic Systems and Quantum Hall Effect | cond-mat.mes-hall | | Abstract: | Kinetic theory of nonlinear current response to an external field is developed for mesoscopic normal metal rings threaded by a magnetic flux. General expressions for direct current (DC) are derived for a non-equilibrium regime. These expressions describe simultaneously a contribution to DC made by a non-equilibrium (external) field, as well as the contribution caused by interaction with intrinsic fields. Contributions of electron-electron and electron-phonon interactions to the direct current in a non-equilibrium systems are studied. The kinetic equation for electrons in a disordered metal ring is solved with taking into account the Coulomb and electron-phonon interactions. This gives an estimate of an overheating of the pumped electron system. | | Source: | arXiv, cond-mat/0206109 | | Services: | Forum | Review | PDF | Favorites | |
