A Schottky diode is formed by the junction of a metal (usually platinum, molybdenum, or chromium) and a semiconductor material (typically n-type silicon). Unlike traditional PN junction diodes, which use a p-n junction, Schottky diodes employ a metal-semiconductor junction. The metal side is called the anode, and the semiconductor side is called the cathode. When
