We study responsivity, sensitivity and response time of plasma wave devices based on Si, GaAs and GaN material systems, and investigate load and bias dependences of the device performance in resonant and non-resonant detection regimes.At room temperature Si MOS is suitable, most probably, for non-resonant detection only. ... mobility in Si I¼ = 500 cm2/Vs, can be obtained as I„ = I¼m/e = 0.055 ps, providing the quality factor, I‰I„ alt; 1, even at f agt; 2 THz. ... Two computer governed Keithley Source meters 2410 were used to apply dc voltage (or current) to the drain and gate contacts of the transistor. ...
