My research interest lies in the field of Terahertz (THz) spectroscopy based on nanogap antennas in a thin metal film for a convergence of optics and electronics. My first approach is to explore optics at nanometer scale for milli-meter wavelengths, in THz region, leading to unprecedented electric field enhancement when the incident long-wavelength light impinges into 1 nm-wide gaps. Atomic layer lithography overcame a technological challenge by combining photolithography and atomic layer deposition (ALD) to create 1-nm-wide vertical gaps that form centimeter-scale loops. This combination of the THz nanotechnology and the wafer-scale nanogap production would enable new and potentially revolutionary experiments at the nanometer regime with high throughput and reproducibility, which will have an immediate and significant impact for fingerprinting of chemical/biological molecules, biomedical and pharmaceutical imaging, 2D material plasmonics, spintronics, topological insulator, and optical cloaking with metamaterials in THz region.
