Abstract

We present our systematic experimental study on the responsivity to THz wave and the noise in the photoconductive antennas made on low-temperature-grown (LTG) GaAs. In particular, we show that both depend on the properties of the LTG GaAs and the type of the metallization. On the basis of the results, we will discuss a device model in a manner independent of the details of the device fabrication to facilitate the standardized description.
