A homojunction is a semiconductor interface that occurs between layers of similar semiconductor material; these materials have equal band gaps but typically have different doping. In most practical cases a homojunction occurs at the interface between an n-type (donor doped) and p-type (acceptor doped) semiconductor such as silicon, this is called a p–n junction.
