Schottky Barrier

A Schottky barrier is an energy barrier formed at the contact between a metal and a semiconductor. When these two materials meet, electrons move from the metal into the semiconductor or vice versa, but only if they have enough energy to overcome this barrier. This barrier controls how easily electrical current flows across the junction, impacting the device's behavior. It's important in electronic components like diodes, where it helps direct current flow in a specific way, enabling fast switching and efficient conduction in certain electronic circuits.
