cond-mat 2110.15369をみて、Landauer-Sharvin resistance(inversely proportional to the number of its conduction channels)なるものの存在を知ったのだった。ballistic conductionの場合はコンダクタンス≒チャンネル数ってことやなあ、なるほど。となった。 こういう感じのメゾスコピック系の「チャンネルを数えるノリ」はopticsとも親和性が良さそうなので、仲良くなりたい気持ち。 ballistic conduction: ballistic conduction (ballistic transport) is the unimpeded flow (or transport) of charge carriers (usually electrons), or energy-carrying particles, over relatively long distances in a material In general, the resistivity of a material exists because an electron, while moving inside a medium, is scattered by impurities, defects, thermal fluctuations of ions in a crystalline solid, or, generally, by any freely-moving atom/molecule composing a gas or liquid....
