…On the other hand, in real semiconductors, the orbital energy varies randomly for each impurity due to various factors (especially electrostatic effects due to other impurity atoms). In 1958, PW Anderson pointed out that the state (and motion) of electrons may change significantly and suddenly depending on the ratio of the average variation in orbital energy to the average interaction energy. This phenomenon is called the Anderson transition. … *Some of the terminology that mentions "Anderson, PW" is listed below. Source | Heibonsha World Encyclopedia 2nd Edition | Information |
…一方,現実の半導体では各種の原因(とくに他の不純物原子による静電的効果)により,軌道のエネルギーは不純物ごとに無秩序に変化している。この軌道エネルギーの平均的ばらつきと相互作用エネルギーの平均値との比に依存して,電子の状態(そして運動)が大きくかつ急激に変化する可能性が1958年にアンダーソンP.W.Andersonによって指摘された。この現象がアンダーソン転移である。… ※「アンダーソン,P.W.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
