We found that upon local injection from the biased EFM tip, charges delocalize over the whole nanotube length (i.e., 1-10 μm), consistent with a capacitive charging of the MWCNT-substrate capacitance. In addition, the insulating layer supporting the nanotubes is shown to act as a charge-sensitive plate for electrons emitted from the MWCNTs at low electric fields, thus allowing the spatial mapping of MWCNT field-emission patterns.Show less >
