Understanding Schottky Barrier Diodes: Function and Applications
A Metal-Semiconductor potential diode is a type of semiconductor device characterized by its low forward voltage and fast switching speed. Unlike traditional p-n junction diodes, it forms a rectifying contact between a metal and a semiconductor – typically a p-type. The height of the barrier is determined by the work function of the metal and the electron affinity of the semiconductor, resulting in a built-in potential. This design leads to reduced majority copyright storage compared to p-n diodes, allowing for faster response times.
