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. How to thank TFD for its existence?

| The conduction electron density and normal-state conductivity are also one to two orders-of-magnitude higher than either the Nb-based alloys or Bi-based cuprates used in present day wires, contradicting the conventional wisdom that good superconductors are poor conductors because of the strong electron-phonon interaction and at the same time providing encouragement that higher [T. Other theorists countered that the spins of conduction electrons are usually randomly oriented, with every up spin canceled by a down spin. Furthermore, the crystallite edges, areas of high conduction electron density, are preferential adsorption sites and therefore, if the carbon black through heat treatment coalesces its crystallites, fewer crystallite boundaries are present and less preferential adsorption sites are available which may explain the decrease in nitrogen adsorption. |
