Nonlinear magnetoconductance of a classical ballistic system | A. V. Andreev

29 Aug 2006 | Subject: | Mesoscopic Systems and Quantum Hall Effect | Abstract: | We study nonlinear transport through a classical ballistic system accounting for the Coulomb interaction between electrons. The joint effect of the applied bias $V$ and magnetic field $H$ on the electron trajectories results in a component of the non-linear current $I(V,H)$ which lacks the $H o -H$ symmetry: $delta I=alpha_{cl} V^2 H$. At zero temperature the magnitude of $alpha_{cl}$ is of the same order as that arising from the quantum interference mechanism. At higher temperatures the classical mechanism is expected to dominate due to its relatively weak temperature dependence. | Source: | arXiv, cond-mat/0608615 | Other source: | [GID 14224] pmid17280452 | Services: | Forum | Review | PDF | Favorites |
