An Etymological Dictionary of Astronomy and Astrophysics
English-French-Persian

The → transfer of an → electron from one → energy level to another.

→ electronic; → transition.

The science dealing with the development and application of → devices and → systems involving the flow of → electrons in a → vacuum, in → gaseous media, and in → semiconductors (Dictionary.com).

→ electron; → -ics.

An electron that is not attached to an → atom, → molecule, or → ion and is free to move under the influence of a present electric or magnetic field.

→ free; → electron.

Same as → Schottky diode

→ hot; → electron; → diode.

The branch of electronics that deals with integrated circuits, especially the interdependence of material, circuits, and design.

Integrated, p.p. of → integrate; → electronics.

An electron that does not experience relativistic effects since its velocity is very small compared to that of light.

→ non-relativistic; → electron.

An electron contained within an atom which may be thought of as orbiting around the nucleus, in a manner analogous to the orbit of a planet around the Sun.

→ orbital; → electron .

An electron emitted from an atom or molecule by an incident photon in the → photoelectric effect.

→ photo-; + → electron.

Electrons ejected from the atoms of a material when bombarded with high energy electrons. Secondary electrons are produced when an incident electron excites an electron in the material and loses some of its energy in the process. The excited electron moves toward the surface of the sample undergoing elastic and inelastic collisions until it reaches the surface, where it can escape if it still has sufficient energy. The secondary electron yield depends on many factors, and is generally higher for high atomic number targets, and at higher angles of incidence.

→ secondary; → electron.

An electron of an atom lying farthest from the nucleus. Valence electrons are shared when atoms combine to form molecules.

→ valence; → electron.
