  • Abstract
    We show that using plasmonic contact electrodes significantly enhances the quantum efficiency of ultrafast photoconductors and demonstrate 50-times higher optical-to-terahertz conversion efficiencies from a plasmonic photoconductive terahertz emitter in comparison with a conventional photoconductive emitter.
