Photovoltages and hot electrons in plasmonic nanogaps
Douglas Natelson, Charlotte I. Evans, Pavlo Zolotavin
In metal nanostructures under illumination, multiple different processes can drive current flow, and in an open- circuit configuration some of these processes lead to the productio…
Substantial local variation of Seebeck coefficient in gold nanowires
Pavlo Zolotavin, Charlotte I. Evans, Douglas Natelson
Nanoscale structuring holds promise to improve thermoelectric properties of materials for energy conversion and photodetection. We report a study of the spatial distribution of the…
Photothermoelectric effects and large photovoltages in plasmonic Au nanowires with nanogaps
Pavlo Zolotavin, Charlotte I. Evans, Douglas Natelson
Nanostructured metals subject to local optical interrogation can generate open-circuit photovoltages potentially useful for energy conversion and photodetection. We report a study…
Plasmonic heating in Au nanowires at low Temperatures: The role of thermal boundary resistance
Pavlo Zolotavin, Alessandro Alabastri, Peter Nordlander +1
Inelastic electron tunneling and surface-enhanced optical spectroscopies at the molecular scale require cryogenic local temperatures even under illumination - conditions that are c…
Current noise enhancement: channel mixing and possible nonequilibrium phonon backaction in atomic-scale Au junctions
Loah A. Stevens, Pavlo Zolotavin, Ruoyu Chen +1
We report measurements of the bias dependence of the Fano factor in ensembles of atomic-scale Au junctions at 77 K. Previous measurements of shot noise at room temperature and low…
Plasmon-assisted photoresponse in Ge-coated bowtie nanojunctions
Kenneth M. Evans, Pavlo Zolotavin, Douglas Natelson
We demonstrate plasmon-enhanced photoconduction in Au bowtie nanojunctions containing nanogaps overlaid with an amorphous Ge film. The role of plasmons in the production of nanogap…
Interplay of bias-driven charging and the vibrational Stark effect in molecular junctions
Yajing Li, Pavlo Zolotavin, Peter Doak +3
We observe large, reversible, bias driven changes in the vibrational energies of PCBM, based on simultaneous transport and surface-enhanced Raman spectroscopy (SERS) measurements o…
