Nettet8. jul. 2024 · If the carbon concentration can be further reduced, the operating voltage of the AlGaN homojunction TJ deep-UV LED can also be further reduced. In addition, it should be emphasized that the doping of a high concentration of Si also reduces the TJ resistivity. Highly doped donors can increase the tunneling probability of AlGaN … 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. This is not a necessary condition as the only requirement is that the same semiconductor (same band …
