Hot electrons arise generically at low temperatures even in degenerate semiconductors or metals.[5] There are a number of models to describe the hot-electron effect.[6] The simplest predicts an electron-phonon (e-p) interaction based on a clean three-dimensional free-electron model. See more Hot carrier injection (HCI) is a phenomenon in solid-state electronic devices where an electron or a “hole” gains sufficient kinetic energy to overcome a potential barrier necessary to break an interface state. The … See more Advances in semiconductor manufacturing techniques and ever increasing demand for faster and more complex See more Hot carrier degradation is fundamentally the same as the ionization radiation effect known as the total dose damage to semiconductors, as … See more The term “hot carrier injection” usually refers to the effect in MOSFETs, where a carrier is injected from the conducting channel in the See more In MOSFETs, hot electrons have sufficient energy to tunnel through the thin gate oxide to show up as gate current, or as substrate leakage current.
