  2. Electronic band structure - Wikipedia

    en.wikipedia.org/wiki/Electronic_band_structure

    Electronic band structure. In solid-state physics, the electronic band structure (or simply band structure) of a solid describes the range of energy levels that electrons may have within it, as well as the ranges of energy that they may not have (called band gaps or forbidden bands).

  3. Valence and conduction bands - Wikipedia

    en.wikipedia.org/wiki/Valence_and_conduction_bands

    In solid-state physics, the valence band and conduction band are the bands closest to the Fermi level, and thus determine the electrical conductivity of the solid. In nonmetals, the valence band is the highest range of electron energies in which electrons are normally present at absolute zero temperature, while the conduction band is the lowest range of vacant electronic states.

  4. Fermi level - Wikipedia

    en.wikipedia.org/wiki/Fermi_level

    The Fermi level of a solid-state body is the thermodynamic work required to add one electron to the body. It is a thermodynamic quantity usually denoted by μ or EF[1] for brevity. The Fermi level does not include the work required to remove the electron from wherever it came from. A precise understanding of the Fermi level—how it relates to ...

  5. Tight binding - Wikipedia

    en.wikipedia.org/wiki/Tight_binding

    t. e. In solid-state physics, the tight-binding model (or TB model) is an approach to the calculation of electronic band structure using an approximate set of wave functions based upon superposition of wave functions for isolated atoms located at each atomic site. The method is closely related to the LCAO method (linear combination of atomic ...

  6. Photonic-crystal fiber - Wikipedia

    en.wikipedia.org/wiki/Photonic-crystal_fiber

    A solid-core fiber is shown with a periodic air hole cladding and a solid blue coating. Photonic-crystal fiber (PCF) is a class of optical fiber based on the properties of photonic crystals. It was first explored in 1996 at University of Bath, UK. Because of its ability to confine light in hollow cores or with confinement characteristics not ...

    Luti-Kriss and debut album (1997–2004) Norma Jean formed in 1997 under the name Luti-Kriss with Josh Scogin on vocals, guitarists Scottie Henry and Chris Day, Josh Swofford on bass, Mick Bailey on turntables, and Daniel Davison on drums. The band recorded a split EP with Travail that was released in 1999 through Pluto Records.

  9. Strongly correlated material - Wikipedia

    en.wikipedia.org/wiki/Strongly_correlated_material

    Typically, strongly correlated materials have incompletely filled d - or f - electron shells with narrow energy bands. One can no longer consider any electron in the material as being in a "sea" of the averaged motion of the others (also known as mean field theory). Each single electron has a complex influence on its neighbors.
