← 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?
A designer lists four junction devices: a photodiode, an LED, a solar cell and a silicon rectifier diode. Which of these is used in reverse bias when it detects light? →
