For these transistors, it is shown for the first time that the maximum of the response (the drain-source photovoltage) shifts with an increasing frequency to the region of higher gate voltages in accordance with the Dyakonov-Shur theory. It is shown that, as temperature is increased to 77 K, the dependence of the photovoltage on the gate voltage becomes nonresonant, which is caused by a decrease in the mobility. %G English %L hal-00540630 %U https://hal.science/hal-00540630 %~ CNRS %~ UNIV-MONTP2 %~ GES %~ UNIV-MONTPELLIER %~ UM1-UM2
