We propose and fabricated a high-electron-mobility-transistor (HEMT) terahertz detector integrated with bow-tie antenna for high current sensitivity. A buried-Pt gate technology was employed for reduction in short channel effect. A high current sensitivity of ~5 A/W at 280 GHz was achieved by 50-nm-gate device. We measured the bandwidth of the HEMT detector by heterodyne mixing with UTC-PD and a frequency multiplier as a radio frequency (RF) and local oscillator (LO), respectively. The intensity of the intermediate signal was measured by changing the frequency of UTC-PD, and a very high bandwidth of up to 26 GHz was obtained. |
