摘要

Part I demonstrated that nano-oxidation in the dynamic-force mode was enhanced by the use of conductive carbon nanotube (CNT) probes. Fabrication of oxide nanostructures using CNT probes benefited not only from the smaller tip apex compared to conventional probes but from improved operational stability over a wide range of exposure conditions primarily due to the hydrophobic nature of the CNT. Here we investigate the bending response of CNT probes to electrostatic and meniscus forces during nano-oxidation. We conclude that bending of the CNT introduces an additional cushion in the combined cantilever-probe deflection system, thus improving overall stability of the tip-sample junction during nano-oxidation.
