Abstract
We have predicted that in suitable multiple barrier structures without applied bias, the thermopower may change sign because of quantum transport process. We have performed detailed numerical calculation to show that the predicted thermopower anomaly can be experimentally observed. This thermopower anomaly does not violate thermodynamic laws.
