  2. Electronic band structure - Wikipedia

    en.wikipedia.org/wiki/Electronic_band_structure

    Energy band gaps can be classified using the wavevectors of the states surrounding the band gap: Direct band gap: the lowest-energy state above the band gap has the same k as the highest-energy state beneath the band gap. Indirect band gap: the closest states above and beneath the band gap do not have the same k value.

  3. Electricity (Orchestral Manoeuvres in the Dark song) - Wikipedia

    en.wikipedia.org/wiki/Electricity_(Orchestral...

    "Electricity" is the 1979 debut single by English electronic band Orchestral Manoeuvres in the Dark (OMD), featured on their eponymous debut album the following year. Andy McCluskey and Paul Humphreys sing the lead vocals on the track together in unison, although Humphreys is positioned higher in the mix .

  4. 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.

  5. Band gap - Wikipedia

    en.wikipedia.org/wiki/Band_gap

    In solid-state physics and solid-state chemistry, a band gap, also called a bandgap or energy gap, is an energy range in a solid where no electronic states exist. In graphs of the electronic band structure of solids, the band gap refers to the energy difference (often expressed in electronvolts ) between the top of the valence band and the ...

  6. Electromagnetic spectrum - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_spectrum

    In frequency (and thus energy), UV rays sit between the violet end of the visible spectrum and the X-ray range. The UV wavelength spectrum ranges from 399 nm to 10 nm and is divided into 3 sections: UVA, UVB, and UVC. UV is the lowest energy range energetic enough to ionize atoms, separating electrons from them, and thus causing chemical reactions.

  7. Electricity (Captain Beefheart song) - Wikipedia

    en.wikipedia.org/wiki/Electricity_(Captain_Beef...

    "Electricity" is a song by Captain Beefheart and his Magic Band, from their 1967 debut album Safe as Milk. Beefheart claimed that A&M Records dropped the band after co-owner Jerry Moss heard the song and declared it "too negative" [4] for his teenage daughter to listen to; Safe as Milk would ultimately be released by Buddah Records.

  8. Electronic properties of graphene - Wikipedia

    en.wikipedia.org/wiki/Electronic_properties_of...

    The conduction and valence bands, respectively, correspond to the different signs. With one p z electron per atom in this model the valence band is fully occupied, while the conduction band is vacant. The two bands touch at the zone corners (the K point in the Brillouin zone), where there is a zero density of states but no band gap. The ...

  9. London Elektricity - Wikipedia

    en.wikipedia.org/wiki/London_Elektricity

    The first incarnation of London Elektricity was the duo Tony Colman and Chris Goss. [2] Founders and backbone of Hospital Records, they also pursued parallel projects under the monikers Peter Nice Trio and Dwarf Electro, [3] but it was their tune "Song in the Key of Knife" under the guise London Elektricity that first gained them widespread recognition.
