Gap-engineered high-performance broad spectral-band plasmonic terahertz detectors for wireless communication.
Photodetectors based on semiconductor surface plasmon polariton (SPP) offer a promising route for high-performance broad spectral-band terahertz (THz) detection by overcoming bandgap limits of conventional semiconductor detectors. However, the active region's dimension of SPP-based photodetectors must be optimized to b...
