Abstract :
We report on an extremely-high sensitive terahertz (THz) detector based on our original asymmetric dual-grating gate high electron mobility transistors (A-DGG HEMTs) designed and fabricated using InAlAs/InGaAs/InP material systems. The obtained responsivity is 22.7 kV/W at 200 GHz. To the best of our knowledge, this value is the record responsivity ever reported for this frequency range at room temperature.
