Considering ideal metal/n-type semiconductor junction diode,
without changing anything else, if the metal is changed so that the
Schottky barrier height increases, how do the following device
parameters change (i.e., increase, decrease, no change, or it
depends)? Explain your answers.
(a) Current at a certain forward voltage.
(b) Capacitance at a certain reverse voltage.
(c) Charge in depletion region in equilibrium (i.e., V = 0
V).
(d) Small-signal dynamic resistance (rd) at a certain forward
current ID = IDQ.
