| Abstract Scope |
Continuing to find more efficient processes of growing carbon nanotubes (CNTs) has become increasingly necessary as they typically have low electrical resistances, high elastic moduli along their long axis, and are hollow with high surface areas. This experiment aims to measure how growth rate decreases as the CNTs grow for extended times up to ten minutes, and at different processing temperatures down to 700 degrees Celsius in order to find the most efficient growth parameters. The purpose of these CNTs are to be used in supercapacitors in conjunction with ionic liquid electrolytes and in 3D photovoltaics as a conductive scaffolding. The CNTs are grown using chemical vapor deposition of acetylene onto a catalyst stack containing an iron catalyst, aluminum, and a titanium diffusion barrier resting on a single-crystal silicon substrate. The CNTs' height is then measured in a scanning electron microscope (SEM) and used to calculate the average growth rate. |
