摘要

利用InAs量子阱(QW) MOSHEMT，利用地-地(GSG)太赫兹探测器探测1.0 THz的太赫兹波。用直流源(地)端不接GSG太赫兹探头地线的探测器得到了清晰的响应曲线。在锁相放大器增益下，响应度达到10755 kV/W，噪声等效功率(NEP)为156 pW/Hz0.5。

1.0 THz detection by InAs quantum-well MOSHEMT using GSG THz probe

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.
