electronic transition
  گذرش ِ الکترونی   
gozareš-e elektroni

Fr.: transition électronique   

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

electronic; → transition.

electronics
  الکترونیک   
elektronik (#)

Fr.: électronique   

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.

free electron
  الکترون ِ آزاد   
elektron-e âzâd (#)

Fr.: électron libre   

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.

hot electron diode
  دیود ِ الکترون ِ داغ   
diod-e elektron-e dâq

Fr.:diode à électrons chauds   

Same as → Schottky diode

hot; → electron; → diode.

integrated electronics
  الکترونیک ِ یکپارچه، ~ دُرُستالیده   
elektronik-e dorostâlidé

Fr.: électronique intégrée   

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

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

non-relativistic electron
  الکترون ِ ناباز‌آنیگی‌مند   
elektron-e nâ-bâzânigi-mand

Fr.: électron non-relativiste   

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

non-relativistic; → electron.

orbital electron
  الکترونِ مداری   
elektron-e madâri (#)

Fr.: électron orbital   

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 .

photoelectron
  شید-الکترون، نور-الکترون   
šid-elektron, nur-elektron

Fr.: photoélectron   

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

photo-; + → electron.

secondary electrons
  الکترون‌های ِ دومان   
elektronhâ-ye dovomân

Fr.: électrons secondaires   

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.

valence electron
  الکترون ِ ارزایی   
elektron-e arzâyi

Fr.: électron de valence   

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

valence; → electron.
