Using Activated Transport in Parallel Nanowires for Energy Harvesting and Hot-Spot Cooling

Year: 2015

Type: article

Abstract: Presently much research is devoted to recapturing waste heat for improved energy efficiency. Here the authors study an array of parallel ``dirty'' semiconductor nanowires, configured as a field-effect transistor. For temperatures at which electrons move in phonon-assisted hops, large figures of merit and output powers are obtained if the impurity bands of the nanowires are depleted by applying a gate voltage. Synergy between phonon activation and gate-tunable particle-hole asymmetry predicts a versatile thermoelectric converter, enabling nanoscale heat management on a chip.
