Résumé |
Due to constraints imposed by the conservation laws, relaxation of hot electrons in quantum wires is suppressed if one considers two-body processes. Finite relaxation can be achieved by three-body collisions. We will consider the cases of screened and unscreened Coulomb interaction and derive the corresponding relaxation rates, that behave as a power laws of temperature. We will also discuss the role of three-body collisions for interaction induced corrections to conductance and thermopower in quantum wires. |
