Electron-positron annihilation — occurs when an electron and a positron (the electron s anti particle) collide. The result of the collision is the conversion of the electron and positron and the creation of gamma ray photons or, less often, other particles. The process must… … Wikipedia
Electron mobility — This article is about the mobility for electrons and holes in metals and semiconductors. For the general concept, see Electrical mobility. In solid state physics, the electron mobility characterizes how quickly an electron can move through a… … Wikipedia
Electron temperature — If the velocities of a group of electrons, e.g. in a plasma, follow a Maxwell Boltzmann distribution, then the electron temperature is well defined as the temperature of that distribution. For other distributions, two thirds of the average energy … Wikipedia
