Problem 1 (10 points) An InP Gunn diode is 10 um long and is operated in the transit-time mode. For InP, the relative permittivity Er = 12.4, the threshold electric field corresponding to the onset of negative differential resistance is Er = 10.5 kV/cm, and the maximum differential mobility dv/dε = -2000 cm?/V.s. Find the minimum electron density that is required for this Gunn diode to generate 10 GHz microwave radiation.
