Abstract

A method for estimating the electrical conductivity of individual carbon nanotubes (CNT), based on modeling of experimental image profiles that are obtained using electrostatic force microscopy (EFM), is proposed. As a result of the profile modeling, the voltage between the tip and CNT was determined as the parameter that characterizes the conductivity of an individual nanotube. A positive correlation between this voltage and the conductivity of individual CNTs was found.
