What Does NEA Stand For?
NEA stands for Negative Electron Affinity
Negative Electron Affinity (NEA) refers to a property of certain materials that allows them to release an electron into the vacuum when they are exposed to sufficient energy, rather than requiring energy to add an electron. This phenomenon enables the direct emission of electrons from a semiconductor surface and is significant in applications such as electron emitters, photodetectors, and advanced electronic devices. NEA materials play a crucial role in enhancing the efficiency of these technologies by facilitating the generation and transport of charge carriers.
