Abstract :
A photoconductive terahertz detector based on plasmonic contact electrodes is experimentally demonstrated. Incorporating plasmonic contact electrodes mitigates the inherent tradeoff between high quantum-efficiency and ultrafast operation, enabling more than 30 times higher terahertz detection sensitivities.
