Conduction Electron

   Also found in: Dictionary/thesaurus, Wikipedia 0.01 sec.
conduction electron [kən′dək·shən i′lek‚trän]
(solid-state physics)
An electron in the conduction band of a solid, where it is free to move under the influence of an electric field. Also known as outer-shell electron; valence electron.

Electron, Conduction 

an electron in metals and semiconductors whose energy lies in a partially filled energy band (the conduction band; seeSOLID). At a temperature of absolute zero there are no electrons in the conduction band of dielectrics and semiconductors. Electrons appear with increased temperature, upon illumination and the introduction of impurities, and under the influence of other external influences.

Conduction electrons always exist in metals, where their concentration is high. When T = 0°K, conduction electrons in metals occupy all the states having energies less than the Fermi energy. It is convenient to describe their characteristics in terms of the kinetic theory of gases by utilizing the concepts of mean free path and frequency of collisions, among others. In semiconductors, where the number of conduction electrons is relatively small, the gas is well described by the classical Boltzmann statistics. In metals, the conduction electrons form a degenerate Fermi liquid.

Moreover, it can be probably said that plasmin causes change in dielectric constant of surrounding medium, which slows the dipole oscillations induced in the conduction electrons of gold nanoparticles.
These "chemical shifts" arise because of the variations in electrostatic screening experienced by core electrons as the valence and conduction electrons are drawn towards or away from the specific atom.
