摘要：
Room temperature electrical transport measurements have been made on suspended multi-walled carbon nanotubes (MWNTs) using a remote controlled manipulation system within a scanning electron microscope. It is shown that the current-voltage characteristics of the MWNTs are symmetric with respect to voltage and that the conductance improves with multiple cycling of the voltage. Estimations of the semiconducting sub-bands and the contact transmission coefficients of the MWNTs have also been made.
