Web2 jan. 2024 · MS Contacts: Introduction • Metal-semiconductor contacts can be ohmic or rectifying (allowing current flow only in one direction). • Ohmic contacts do not limit current flowing in both directions (I-V curve may not need to be linearly related). • Rectifying contacts, generally called Schottky barrier diodes, limit current flowing in one direction.

In 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 can either be rectifying or non-rectifying. The rectifying metal–semiconductor junction forms a Schottky barrier, making a device known as a Schottky diode, while the non-rectifying junction is called an ohmic contact. (In contrast, a rectifying sem…
