Abstract
A theoretical analysis of the Peltier effect in two-dimensional quantum poi nt contacts, in field-free conditions and under the influence of applied ma gnetic fields, is presented. It is shown that in the nonlinear regime (fini te applied voltage) new peaks in the Peltier coefficient appear leading to violation of Onsager's relation. Oscillations of the Peltier coefficient in a magnetic field are demonstrated. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
