band theory — In chemistry and physics, a theoretical model describing the states of electrons in solid materials, which can have energy values only within certain specific ranges, called bands. Ranges of energy between two allowed bands are called forbidden… … Universalium
solids, mechanics of — ▪ physics Introduction science concerned with the stressing (stress), deformation (deformation and flow), and failure of solid materials and structures. What, then, is a solid? Any material, fluid or solid, can support normal forces.… … Universalium
Electronic band structure — In solid state physics, the electronic band structure (or simply band structure) of a solid describes ranges of energy that an electron is forbidden or allowed to have. It is due to the diffraction of the quantum mechanical electron waves in the… … Wikipedia
K·p perturbation theory — In solid state physics, k·p perturbation theory is an approximation scheme for calculating the band structure (particularly effective mass) and optical properties of crystalline solids. It is pronounced k dot p , and is also called the k·p method … Wikipedia
Valence band — In solids, the valence band is the highest range of electron energies where electrons are normally present at absolute zero. In semiconductors and insulators, there is a band gap above the valence band, followed by a conduction band above that.… … Wikipedia
Conduction band — In the solid state physics field of semiconductors and insulators, the conduction band is the range of electron energies, higher than that of the valence band, sufficient to free an electron from binding with its individual atom and allow it to… … Wikipedia
Mattis–Bardeen theory — The Mattis–Bardeen theory is a possible explanation of a phenomenon observed in superconductors. Contents 1 Introduction 2 The response to the electromagnetic wave 3 Use in Optical Study 4 Referen … Wikipedia
Atomic theory — Atomic model redirects here. For the unrelated term in mathematical logic, see Atomic model (mathematical logic). This article is about the historical models of the atom. For a history of the study of how atoms combine to form molecules, see… … Wikipedia
HSAB theory — The HSAB concept is an acronym for hard and soft (Lewis) acids and bases. Also known as the Pearson acid base concept, HSAB is widely used in chemistry for explaining stability of compounds, reaction mechanisms and pathways. It assigns the terms… … Wikipedia
Adjustable gastric band — A laparoscopic adjustable gastric band is a restrictive device implanted via bariatric surgery and designed for obese patients with a body mass index (BMI) of 40 or greater mdash;or between 35 ndash;40 in cases of patients with certain… … Wikipedia
