Space charge — is a concept in which excess electric charge is treated as a continuum of charge distributed over a region of space (either a volume or an area) rather than distinct point like charges. This model typically applies when charge carriers have been… … Wikipedia
Electron beam lithography — (often abbreviated as e beam lithography) is the practice of scanning a beam of electrons in a patterned fashion across a surface covered with a film (called the resist),cite book |last= McCord |first=M. A. |coauthors=M. J. Rooks |title=… … Wikipedia
Electron transfer — (ET) is the process by which an electron moves from one atom or molecule to another atom or molecule. ET is a mechanistic description of the thermodynamic concept of redox, wherein the oxidation states of both reaction partners change. Numerous… … Wikipedia
Electron cooling — is a process to shrink the size, divergence, and energy spread of charged particle beams without removing particles from the beam. Since the number of particles remains unchanged and the space coordinates and their derivatives (angles) are… … Wikipedia
Electron capture — (sometimes called inverse beta decay) is a decay mode for isotopes that will occur when there are too many protons in the nucleus of an atom and insufficient energy to emit a positron; however, it continues to be a viable decay mode for… … Wikipedia
Electron beam processing — involves irradiation of products using a high energy electron beam accelerator. Electron beam accelerators utilize an on off technology, with a common design being similar to that of a cathode ray television.Electron beam processing is used in… … Wikipedia
