Low Temperature Locally-Controlled Growth of Wide Bandgap Nitride and Diamond Films via Plasmon Resonance-Excited Kinetic Processes.

摘要

Our LOCO research program explores two closely related projects that seek to employ resonant plasmonic phenomenon for the generation of low-temperature, electrochemical and photochemical potentials within the optical near-field of nanoscale plasmonic structures. We have worked to develop a plasmon-driven source for controlled deposition of nitrogen precursors for low temperature nitride film growth using cryogenically cooled, plasmonically active patterned substracts. Separately, we have also performed theoretical and experimental identification of a newly described optoelectronic phenomenon, termed the "plasmoelectric effect", whereby plasmonic excitation of metal nanostructures can directly induce electrochemical potentials for electro-reduction and other forms of electrical work.
