| Popis: | Terahertz wave of 1.0 THz using ground-signal-ground (GSG) THz probe was detected by InAs quantum-well (QW) MOSHEMT. The clear response curves were obtained by the detector of which DC source (ground) terminal unconnected to the ground line of GSG THz probe. The responsivity of 10,755 kV/W with lock-in amplifier gain was achieved and noise equivalent power (NEP) of 156 pW/Hz0.5 was estimated. |
