SUMMARY
A Schottky barrier or contact is a junction formed between a metal and a semiconductor, specifically either an N-type or P-type semiconductor. Unlike traditional diodes, which consist of a junction between P-type and N-type materials, Schottky diodes utilize a metal-semiconductor interface, resulting in faster operation and a lower forward voltage drop. A practical example is the Cat Whisker Diode used in crystal radios, which employs a metal contact with Germanium. Understanding Schottky barriers requires foundational knowledge in semiconductor physics.
