Abstract
The new doubly interdigitated grating gate high-electron-mobility transistor (HEMT) has been subjected at room temperature to a 1.5 μm cw laser beam. The observed photoresponse shows a threshold behavior as a function of drain-to-source bias for different gate voltages. The result was interpreted as a clear signature of the self-oscillation of plasma waves.
