Wave Functions of the Conduction Electrons in Crystalline Aluminium

The Bonding Electron Density in Aluminum

“…The Bonding Electron Density in Aluminum Philip N. H. Nakashima, 1,2,3 * Andrew E. Smith, 1,4 Joanne Etheridge, 2,3 Barrington C. Muddle 1,2 Aluminum is considered to approach an "ideal" metal or free electron gas. The valence electrons move freely, as if unaffected by the presence of the metal ions.…”

“…In metals, the widely taught concept of an ideal metal or free electron gas is popularly expressed as a regular array of metal ions surrounded by a sea of delocalized valence electrons (1). Although a gross simplification, this model is often sufficient to give a qualitative account of many characteristic properties of metals such as their high electrical and thermal conductivities and lustrous or shiny appearance (1)(2)(3). However, it fails to explain the often strong variation in particular properties of different metals that are sensitive to electronic structure (2-4)-for example, the anisotropy of elastic constants.…”

“…The large global effort invested in refining aluminum and its alloys to extend property profiles involves the need for a fundamental understanding of metallic structure in solid solutions and structural evolution at the nanoscale in multiphase alloys. Such an effort must begin with accurate knowledge of the electronic structure, chemical bond-ing, and atomic-scale mechanics in pure aluminum (2)(3)(4)(7)(8)(9)(10)(11)(12), and then ultimately extend to its alloys (2,8,9,13).…”

The X-ray Debye temperature of aluminum

“…A preliminary account of this work has appeared (Median, Dingle & Field, 1969) and part of it is available in more detail elsewhere (Dingle, 1969).…”
