Freeelectron in physics may refer to: Electron, as a free particle Solvated electron Charge carrier, as carriers of electric charge Valence electron...
In solid-state physics, the freeelectron model is a quantum mechanical model for the behaviour of charge carriers in a metallic solid. It was developed...
The electron ( e− or β− ) is a subatomic particle with a negative one elementary electric charge. Electrons belong to the first generation of the lepton...
In chemistry, a lone pair refers to a pair of valence electrons that are not shared with another atom in a covalent bond and is sometimes called an unshared...
the nearly freeelectron model (or NFE model and quasi-freeelectron model) is a quantum mechanical model of physical properties of electrons that can move...
An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is defined as the net...
field, V/m. When a potential difference is applied across a conductor, freeelectrons gain velocity in the direction, opposite to the electric field between...
complementary models for electrons in solids.: 161 The first one is the nearly freeelectron model, in which the electrons are assumed to move almost...
In chemistry and physics, valence electrons are electrons in the outermost shell of an atom, and that can participate in the formation of a chemical bond...
spontaneous molecule collisions, where each generated pair consists of a freeelectron and a positive ion. Ions are also created by chemical interactions,...
particles. Usual models are the freeelectron model and the nearly freeelectron model. In the appropriate systems, the freeelectron pressure can be calculated;...
Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a method for studying materials that have unpaired electrons. The...
electrons (in the form of an electron cloud of delocalized electrons) and positively charged metal ions. It may be described as the sharing of free electrons...
An electron transport chain (ETC) is a series of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors...
sometimes called the electron heat capacity, is the specific heat of an electron gas. Heat is transported by phonons and by freeelectrons in solids. For pure...
sometimes referred to as free–free radiation. This refers to the fact that the radiation in this case is created by electrons that are free (i.e., not in an atomic...
Field electron emission, also known as field emission (FE) and electron field emission, is emission of electrons induced by an electrostatic field. The...
molecular states, FELs use a relativistic electron beam as the lasing medium, hence the term free-electron. The pursuit of a high-quantum-energy laser...
physics, it refers to freeelectrons that facilitate electrical conduction. In quantum chemistry, it refers to molecular orbital electrons that have extended...
can be described as an instability in the dielectric function of a freeelectron gas. The frequency depends only weakly on the wavelength of the oscillation...
crystal. When a doped semiconductor contains free holes, it is called "p-type", and when it contains freeelectrons, it is known as "n-type". The semiconductor...
An electron gun (also called electron emitter) is an electrical component in some vacuum tubes that produces a narrow, collimated electron beam that has...
