Low-Frequency Noise in Carbon-Nanotube/Cellulose Composite Paper

Abstract

Low-frequency noise characteristics for carbon-nanotube (CNT)/cellulose composite paper were experimentally investigated. The measured low-frequency noise exhibited 1/ f characteristics and can be explained by Hooge's empirical law. Large noise coefficients suggested that CNT–CNT junctions, not the CNTs themselves, are the dominant source of 1/ f noise in the composite paper.
