✦ Synopsis

Abstract

It is shown that the dominant conduction mechanism in single‐wall carbon nanotube networks at room temperature is variable range hopping. Thin networks follow a variable range hopping law throughout the temperature range 4 K < T < 300 K, thick networks display variable range hopping characteristics in the range 50 K < T < 300 K, with deviation to Bloch–GrΓΌneisen behaviour at lower temperatures. The adsorption state of these materials is shown to determine the sign of change in conductance upon subsequent exposure to oxygen. (Β© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
