Quantum dot as thermal rectifier
arXiv:cond-mat/0703514 · doi:10.1088/1367-2630/10/8/083016
Abstract
We report the observation of thermal rectification in a semiconductor quantum dot, as inferred from the asymmetric line shape of the thermopower oscillations. The asymmetry is observed at high in-plane magnetic fields and caused by the presence of a high orbital momentum state in the dot.
