چکیده
|
In this paper, we report the detection of sub-thz (300 ghz) radiation by using high electron mobility transistor (hemt). the observation of photoresponse are measured against gate voltage. the measured photoresponse is a superposition of a generally increasing response with a decrease in vgs coupled with a small peak approximately at threshold. the response has also been measured as a function of current, frequency and rf input power and there is evidence that the hemt can be a sensitive sub- thz detector.
