Research Interests
We study subwavelength confinement of electromagnetic wave and their nonlinearity in nanometer and angstrom-scale antennas. By using a new patterning technology based on atomic layer deposition, chemical vapor deposition and simple adhesive tape-based planarization creates vertically oriented gaps in opaque metal film along the entire contour of a millimeter-sized pattern with gap widths less than a nanometer. Squeezing terahertz electromagnetic waves through these nanometer and angstrom-scale gaps leads to giant field enhancements, nonlocal electromagnetic effects and light-induced electron tunneling.
