Résumé:

—We present the low frequency noise and the photoresponse in InP double heterojunction bipolar transistor (DHBT) THz detectors. A current responsivity of 0.23 A/W and a noise equivalent power of 4·10-10 W/Hz 1/2 have been measured at 1 kHz modulation frequency. The collector bias can substantially reduce the noise equivalent power.
