Schottky barrier

https://doi.org/10.1351/goldbook.08870
Potential energy barrier at a semiconductor-metal junction with the current rectifying characteristics.
Note:
The diode based on the Schottky barrier is a Schottky diode or a hot carrier diode. Schottky diodes show switching times down to below 1 ns and a low applied potential drop (0.15 to 0.45 V).
