Microwave plasma enhanced CVD has reproducibly yielded Single-walled and Multiwalled carbon nanotubes. This development has provided access to new parameter space and an opportunity for better control over the nanotube properties. SWCNTs were grown at 600-800oC using a mix of methane and hydrogen gas. The catalyst was bimetallic Mo/Co supported on MgO and dispersed on a silicon wafer. MWCNT’s were characterized using spectroscopic ellipsometry. The impact of thermodynamic calculation and plasma chemistry on control of CNT properties will be presented.
