WebMar 23, 2024 · A Schottky diode is sometimes called a Schottky barrier diode, or simply a barrier diode. These diodes are built by placing a metal film in contact with a semiconductor layer (normally n-type). These diodes are forward biased when the metal side is held at higher potential than the semiconductor side, and vice versa for reverse bias.
