Universal conductance fluctuations : ウィキペディア英語版 | Universal conductance fluctuations Universal conductance fluctuations (UCF) in quantum physics is a phenomenon encountered in electrical transport experiments in mesoscopic species. The measured electrical conductance will vary from sample to sample, mainly due to inhomogeneous scattering sites. Fluctuations originate from coherence effects for electronic wavefunctions and thus the phase-coherence length needs be larger than the momentum relaxation length . UCF is more profound when electrical transport is in weak localization regime. 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「Universal conductance fluctuations」の詳細全文を読む
