ABSTRACT
ABSTRACT
We discuss terahertz nano phenomena whereby millimeter waves funnel through nano antennas enhancing molecular cross sections by more than 103; enhancing nonlinearities and lowering transition temperatures of vanadium dioxide; creating intensity enhancements of 109. We push this technology into one-nanometer regime using atomic layer deposition combined with photolithography and exfoliation. One-centimeter long, one-nanometer wide gaps, essentially infinitely long for the purpose of terahertz applications, are fabricated. Nano and terahertz technologies have much to offer to each other, providing insights into the smallest possible gaps interacting with largest available wavelengths, with both fundamental and application implications.
Note: Pizza and refreshments will also be provided.
