A single crystal of semiconductor material, part doped with N type impurities and part doped with P type impurities, with the N and P types meeting at a single junction. This junction conducts only when forward biased.
Such a diode may be an independent discrete component or it may be part of an integrated circuit (in which case the entire integrated circuit is the single crystal).
A Shockley diode uses a metal-semiconductor junction instead of a p-n semiconductor-semiconductor junction. This results in a device with a much lower forward bias voltage drop and much faster switching times.
That is a DIODE, which can be of any of these types:P-N junction (shown above)point contactschottky barrier (i.e. metal-semiconductor junction)
uni junction transistor
It can be either a junction or point contact diode built with semiconductor material. there are many types depending on intended usage.junction diode is produced as described in its name by forming a junction in the semiconductor by using opposite types of dopant impurities.point contact diode is produced as described in its name by taking a semiconductor base and pressing a sharp metal point on its surface.A few of the types of semiconductor diodes are: small signal, power rectifier, zener, tunnel, gunn, etc.
The theory of diode operation is based on the principles of semiconductor physics, particularly the p-n junction. A diode consists of p-type and n-type semiconductor materials joined together, creating a junction where electrons and holes recombine. When forward-biased, the diode allows current to flow easily as the applied voltage reduces the barrier potential, enabling charge carriers to move across the junction. Conversely, when reverse-biased, the diode blocks current flow, as the barrier potential increases, preventing charge carriers from crossing the junction.

The voltage across a forward-biased PN junction in a semiconductor diode or transistor.

A diode has a n type and a p type materials that's why it's called a pn-junction device
