Electron emission from solids (I): History & Theory

Certain solids emit electrons from their surfaces when subjected to heat (thermionic emission), electromagnetic radiation (photoemission) and/or an electric field (field emission). Much of electronics, including vacuum tubes, cathode-ray tubes in their various manifestations, and electron microscopes, depend on the emission of electrons from metals and the manipulation of these electrons to perform various tasks.
