Abstract:

We assembled nanocapacitors with large dielectric strength to a nanoscale rechargeable battery. We fabricated arrays of one-, two- and three-dimensional synthetic atoms and comparison of its performance data with theoretical predictions. We investigated recovery of alumina nanocapacitors after high-voltage breakdown. Previously we had discovered that Al2O3 nanocapacitors can self-repair. Recently we discovered that our newly fabricated SiO2nanocapacitors can self-repair. We found a significant reduction of leak currents and an increased dielectric strength due to coulomb blockade in nanocapacitors. On the theory side, we are making great progress. We computed the leak currents for synthetic atoms in one, and three dimensions. We filed several disclosures.
