Abstract

Part I demonstrated that nano-oxidation in the dynamic-force mode was enhanced by theuse of conductive carbon nanotube (CNT) probes. Fabrication of oxide nanostructuresusing CNT probes benefited not only from the smaller tip apex compared toconventional probes but from improved operational stability over a wide range ofexposure conditions primarily due to the hydrophobic nature of the CNT. Here weinvestigate the bending response of CNT probes to electrostatic and meniscusforces during nano-oxidation. We conclude that bending of the CNT introducesan additional cushion in the combined cantilever-probe deflection system, thusimproving overall stability of the tip–sample junction during nano-oxidation.
