Metal-Semiconductors Contacts - Engineering LibreTexts
WEBAs the name implies, the MS junction is that a metal and a semiconductor material are contacted closely. Basically, there are two types of MS contacts that are widely used in semiconductor devices: Rectifying Schottky Diodes. Non-rectifying Ohmic contact.
Metal–semiconductor junction - Wikipedia
WEBIn solid-state physics, a metal–semiconductor (M–S) junction is a type of electrical junction in which a metal comes in close contact with a semiconductor material. It is the oldest practical semiconductor device. M–S junctions …
WEBThe metal–semiconductor junction can be a rectifying junction or an ohmic contact. The latter is of growing importance to the design of high-performance transistors. PART I: PN JUNCTION.
WEBWhat happens in a metal-semiconductor junction when you ap ply a voltage to the metal with respect to the semiconductor? In a metal-semiconductor junction under bias, is there current flow? If so, how exactly does it happen? Cite as: Jesús del Alamo, course materials for 6.720J Integrated Microelectronic Devices, Spring 2007. 1.

22.9: Metal–Semiconductor Junction – Ohmic Contact
WEBWhen a metal and an n-type semiconductor are joined and Φ M < Φ S, electrons will flow from the Fermi energy level in the metal into the semiconductor conduction band to lower their energy. This will cause the chemical potential of the semiconductor to move up into equilibrium with that of the metal.
