Atomic Force Microscopy (AFM) is one of the powerful techniques for imaging, measuring and manipulating matter at the nanoscale. In general, the structure of AFM probes is effect for molecular and sub-molecular resolution. Previous studies have attempted to attach or grow CNTs to improve the resolution of AFM. Boron Nitride Nanotubes (BNNTs) is a material with properties similar to CNTs, such as mechanical properties, thermal conductivity and thermal expansion. In our study, we have generated nano-sized catalyst arrays on the substrate by dip-pen nanolithography (DPN) technique and coated catalyst on the tip by the reverse DPN method. We demonstrate the growth of BNNTs in the chemical vapor deposition (CVD) process. All analyses were performed using AFM and scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). [This was supported by Korea National University of Transportation in 2019.] |
