The Mott criterion describes the critical point of the metal-insulator transition. The criterion is where is the electron density of the material and the effective bohr radius. The constant , according to various estimates, is 2.0, 2.78,4.0, or 4.2. If the criterion is satisfied (i.e. if the density of electrons is sufficiently high) the material becomes conductive (metal) and otherwise it will be an insulator. 〔 〕 ==See also== *Hubbard model *Mottness *Bohr Radius *Mott Insulator 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Mott Criterion」の詳細全文を読む スポンサード リンク
