To Plot the V-I Characteristics of Gunn Diode.

GaAs is used in the fabrication of GUNN diodes because:
The electrodes of a Gunn diode are made of:
The mode of operation in which the Gunn diode is not stable is:
The negative resistance in Gunn diode is due to
In Gunn diode oscillator, the Gunn diode is inserted into a waveguide cavity formed by a short circuit termination at one end
