摘要
Almost 100% pure double-walled carbon nanotube (DWNT) was successfully synthesized by optimizing the catalyst composition of Co/Fe/ Mo in a chemical vapor deposition (CVD) growth system with a post-growth purification process. The Raman scattering spectra of the product showed characteristic features of DWNT. The radial breathing modes were analyzed well by a simple analytic model considering the interwall interaction.
