  7. Electronic band structure

    12 Apr 2010 | | Contributor(s):: Saumitra Raj Mehrotra, Gerhard Klimeck

    In solid-state physics, the electronic band structure (or simply band structure) of a solid describes ranges of energy in which an electron is "forbidden" or "allowed". The band structure is also often called the dispersion or the E(k) relationship. It is a mathematical relationship between the...
