A heterojunction is an interface between two layers or regions of dissimilar semiconductors. These semiconducting materials have unequal band gaps as opposed to a homojunction. It is often advantageous to engineer the electronic energy bands in many solid-state device applications, including semiconductor lasers, solar cells and transistors. The combination of multiple heterojunctions together in a device is called a heterostructure, although the two terms are com

It is often advantageous to engineer the electronic energy bands in many solid-state device applications, including semiconductor lasers, solar cells and transistors.
What is a heterojunction?
Generally, a heterojunction is an interface region between two different semiconductors with unequal band structures. The behaviors of the heterojunction strongly depend on the band alignment at the interface.
What is an abrupt heterojunction?
Part of the book series: NATO ASI Series ( (NSSE,volume 87)) The central aspect of an abrupt heterojunction, and the point of departure for all its device properties, is the exact lineup of the bands of the two semiconductors at the interface. Band lineups vary over a wide range.
What is the difference between homojunction and heterojunction?
A P-N junction that encompasses two different semiconductors is called a heterojunction. The most distinctive feature of such junctions is that the P and the N region have different energy band gaps. A junction containing only one semiconductor, such as a classical silicon PN junction, is called a homojunction.
