| Popis: | 106 It is very important to design novel heat diodes in the control of heat currents. So far, few literatures have experimentally reported the heat rectification feature of such devices. Although some theoretical concepts considering phonon carriers to carry heat currents have been proposed to design heat diodes, these proposals are not easy to be implemented by experiments. This thesis considers the structure of quantum dot superlattice nanowires with staircase energy levels and theoretically demonstrates that electron heat currents show a heat rectification behavior. To have a high efficient electron heat diode, phonon heat currents should be fully blocked. |
