Definition of Schottky barrier in English:

Schottky barrier


  • An electrostatic depletion layer formed at the junction of a metal and a semiconductor, which causes it to act as an electrical rectifier.

    • ‘The experimental results conclude that the adjacent MSM interfaces are two Schottky barriers, which serve as two back-to-back diodes.’
    • ‘The key to the new receiver is an HEB, which suffers from only about one-tenth of the noise of the Schottky barrier receivers previously used to detect terahertz radiation.’
    • ‘The thickness of 0.55 mm (max.) is the smallest for Schottky barrier diodes performing rectification with a rectified current of 1A.’


1940s: named after Walter Schottky (1886–1976), German physicist.
