Role of metallic leads and electronic degeneracies in thermoelectric power generation in quantum dots
Year: 2020
Type: article
Abstract: The heat-to-energy conversion efficiency of a thermoelectric nanodevice - which can be quantified by the power factor - is substantially influenced by intrinsic device characteristics in zero-dimensional systems. Using an electroburned graphene quantum dot, the authors demonstrate that controlling the spin degeneracy of the quantum dot and its coupling to the electrodes can increase the power factor considerably. In addition, the adverse effect of non-ideal heat exchanging contacts which suppress the power factor is studied.
