jellium model

jellium model

[′jel·ē·əm ‚mäd·əl]
(physical chemistry)
A model describing the delocalized valence electrons in a metallic atom cluster in which the positive charge is regarded as being smeared out over the entire volume of the cluster while the valence electrons are free to move within this homogeneously distributed, positively charged background.
(solid-state physics)
A model of electron-electron interactions in a metal in which the positive charge associated with the ion cores immersed in the sea of conduction electrons is replaced by a uniform positive background charge terminating along a plane that represents the surface of the metal.

A more realistic single-electron potential U(r) can be constructed in the framework of the jellium model [4,5,15] as a sum of the positive contribution of the carbon atom's nuclei located on the spherical surface of the fullerene radius R and the negative contribution of the electron clouds.

have explained the stability of small [Al.sub.n] clusters by using jellium model because of the valence electrons of Al-like free electron [1, 2].
Then, in the limit of constant density of deconfined magnetic charges, the corresponding dual electric charge system could be the jellium model of an electronic gas.
By using this simplified 'Jellium Model' one could thus understand about their physical and chemical properties which in essence could be simply modified by changing their size alone.
