Explain dielectric breakdown

WebIn a dielectric, the charges are valence electrons that are stuck inside atoms of a crystal or polymer, and so current doesn’t flow at all. The electric field, however, still exerts a force on the charges. While the individual electrons remain tied to their parent atoms, they prefer … WebStructures for a single-photon avalanche diode and methods of forming a structure for a single-photon avalanche diode. The structure includes a semiconductor layer having a first well and a second well defining a p-n junction with the first well, and an interlayer dielectric layer on the semiconductor layer. A deep trench isolation region includes a conductor …
