Photoconductive response of a single Au nanorod coupled to LaAlO3/SrTiO3 nanowires. Jnawali, G., Chen, L., Huang, M., Lee, H., Ryu, S., Podkaminer, J. P., Eom, C., Irvin, P., & Levy, J. APPLIED PHYSICS LETTERS, MAY 25, 2015. doi abstract bibtex Terahertz (THz) spectroscopy is an important tool that provides resonant access to free carrier motion, molecular rotation, lattice vibrations, excitonic, spin, and other degrees of freedom. Current methods using THz radiation suffer from limits due to diffraction or low-sensitivity, preventing application at the scale of single nanoscale objects. Here, we present coupling between plasmonic degrees of freedom in a single gold nanorod and broadband THz emission generated from a proximal LaAlO3/SrTiO3 nanostructure. A strong enhancement of THz emission is measured for incident radiation that is linearly polarized along the long axis of the nanorod. This demonstration paves the way for the investigation of near-field plasmonic coupling in a variety of molecular-scale systems. (C) 2015 AIP Publishing LLC.
