Universal Conductance Fluctuations
- Universal Conductance Fluctuations
Universal Conductance Fluctuation (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 smaller than the momentum relaxation length . UCF is more profound when electrical transport is in weak localization regime.
