Research Abstract

Independent control of CNT diameter and length in a thermal Chemical Vapor Deposition (CVD) process is performed with a low pressure Differential Mobility Analyzer (DMA). CNT diameter is controlled by employing size selected catalyst metal nanoparticles. The nanoparticles are generated by laser vaporization and classified by a DMA which sorts them by diameter according to differences in electrical mobility. Controlling of CNT length is also applied to diameter controlled CNT by using tandem DMA system. This technique will contribute to on-line monitoring or preparation of standard substance of nano wire materials
