Abstract :
Plasmonic antennas at THz frequencies are promising candidates to enhance the sensitivity of THz detectors. The resonances of metallic and semiconductor antennas are compared. Experiments show the powerful advantage of semiconductors as a means for active control over the localized surface plasmons.
