Abstract

Thermopower of a solid-state caterpillar Sinai billiard is experimentally investigated. Observed commensurability oscillations of magnetothermopower are much more pronounced than those of magnetoresistance. The magnetothermopower anomalies are adequately described by the Mott formula for the hard-wall billiard model. Computer simulation of a map, relating initial conditions of electrons, injected into the billiard to corresponding outgoing probe, has made it possible to reveal specific trajectories responsible for the observed features.
