High Resolution Image with Multi-wall Carbon Nanotube Atomic Force Microscopy Tip

In this paper, a simple and reproducible approach for attaching the multi-wall carbon nanotubes (MWNTs) to the apex of the atomic force microscope probe has been proposed. For this purpose, thedielectrophoresis method was applied due to its simple performance, cheapness and reliability. Here,specifically the effect of voltage on the deposition of MWNTs onto the tip of the atomic force microscope has been investigated while the other parameters held constant. Our experiments revealed that when the frequency was held at 5 MHz and 1 μL of MWNTs solution injected, the optimum voltage between tip and electrode surface was 6 V
