The reverse current of a silicon diode is a few nanoampere at 300 K. A designer warms the diode to a higher temperature with the reverse voltage kept fixed. How does the reverse current change, and why?
It rises, because heat makes more minority carriers
It falls, because the barrier is higher
It stays the same, because it depends only on the voltage
It rises, because the majority carriers cross the barrier
