Metal-semiconductor contacts are an obvious component of any semiconductor device. At the same time, such contacts cannot be assumed to have a resistance as low as that of two connected metals.
In particular, a large mismatch between the Fermi energy of the metal and semiconductor can result is a high-resistance rectifying contact. The metal-semiconductor (MS) contact is an important component in the performance of most semiconductor devices in the solid state. As 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. Metal - Semiconductor Contacts and Devices (VLSI Electronics Microstructure Science Book 13) - Kindle edition by Simon S.

The emphasis is placed on the interplay. Lecture 19 - Metal-Semiconductor Junction (cont.) March 19, Contents: 1. Schottky diode 2. Ohmic contact • What does one have to do for a metal-semiconductor junction to become an ohmic contact.
• Why do ohmic contacts look as S = ∞ for minority carriers. Cite as: Jesús del Alamo, course materials for J Integrated. An ohmic contact is a non-rectifying electrical junction: a junction between two conductors that has a linear current–voltage (I-V) curve as with Ohm's ellomultimidia.com resistance ohmic contacts are used to allow charge to flow easily in both directions between the two conductors, without blocking due to rectification or excess power dissipation due to voltage thresholds.
