We report the observation of a thermoelectric
power factor in InAs
nanowires that exceeds that predicted by a single-band bulk model
by up to an order of magnitude at temperatures below about 20 K. We
attribute this enhancement effect not to the long-predicted 1D subband
effects but to quantum-dot-like states that form in electrostatically
nonuniform nanowires as a result of interference between propagating
states and 0D resonances.
