Heterojunction - Wikipedia
网页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 …
Heterojunction - an overview | ScienceDirect Topics
网页Heterojunction is the interface area formed by the contact of two different semiconductors. The semiconductor heterojunction is a special type of PN junction, which is formed by sequentially depositing two or more layers of different semiconductor film materials on the same substrate.

Heterojunctions - an overview | ScienceDirect Topics
网页A heterojunction is created when two materials, usually a metal and semiconductor, or two semiconductors, are joined together. At the heterojunction, there are discontinuities in both the CB and VB, which is the origin of the most useful properties like enhancement of spatial charge separation and photocatalytic activity [73,74].
Recent advances in semiconductor heterojunctions: a detailed …
网页Various types of heterojunctions, such as the Schottky barrier, p–n (or non-p–n), van der Waals and facet heterojunctions, can be fabricated depending on specific applications. Each type of heterojunction has its advantages and limitations; hence, proper choice of heterojunction is essential.
Recent Advances in Semiconductor Heterojunctions and Z
网页The present article reviews recent trends in semiconductor heterojunctions and Z-schemes with a focus on hydrogen generation and water splitting, exhibiting specific needs for charge carrier separation. We also included recent material trends, i.e. 2D/2D combinations, direct Z-schemes, MOFs and COFs, and combinations with upconversion materials.
