a) At VD =0 Volts, which diode has the wider total depletion region width (value
(in microns) and what is it?
b) At Vp =0 Volts, in which diode the magnitude of the maximum electric field in
the depletion region is the largest and what is its value (in V/cm)?
c) Under a reverse bias Vp <0, which diode will breakdown first (i.e. at a
