Schottky Diode Lab


From the LED Lab, we saw that a PN junction is a diode – that is, when a P-type semiconductor contacts an N-type semiconductor. However, it turns out that a metal and a semiconductor can also form a diode, known as a Schottky diode.

Because of the metal-semiconductor junction, Schottky diodes typically have much faster switching and lower forward voltage drop than traditional diodes.

For this lab, gold particles will be evaporated onto the N-type silicon substrate.
