Abstract:Carbon Nanotubes (CNT) were synthesized at room temperature conditions on a heated scanning probe without the use of conventional Chemical Vapor Deposition (CVD) apparatus or the process gases. The heated scanning probe is composed of doped silicon with heater integrated into the end of cantilever. Dip pen techniques were utilized for the deposition of fullerene and metal catalyst layers on the scanning probes. Initially a layer of fullerene (C60) was deposited on the scanning probe tip using a microfluidics inkwell apparatus and then catalyst precursors were deposited in the form of aqueous solutions of metal salts prior to the synthesis of CNTs. To avoid the oxidation of coated fullerene layer over the heated scanning probes at elevated temperatures of 350-500 C, CNTs were synthesized under inert atmospheric conditions. The synthesized CNTs were further characterized using Scanning Electron Microscopy (SEM) and Raman Spectroscopy.
