翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Thermal conductance quantum ： ウィキペディア英語版 Thermal conductance quantum In physics, the thermal conductance quantum $g\_0$ describes the rate at which heat is transported through a single ballistic phonon channel. It is given by: $g\_\; =\; \backslash frac\; \backslash approx\; (9.456\backslash times10^\; W/K^)T$. The thermal conductance of any electrically insulating structure that exhibits ballistic phonon transport is a positive integer multiple of $g\_0$. The thermal conductance quantum was first measured in 2000. These measurements employed suspended silicon nitride nanostructures that exhibited a constant thermal conductance of 16$g\_0$ at temperatures below approximately 0.6 kelvin. For ballistic electrical conductors, the electron contribution to the thermal conductance is also quantized as a result of the electrical conductance quantum and the Wiedemann–Franz law. ==References== 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「Thermal conductance quantum」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
