Abstract
A system is provided that can be utilized to generate nanotubes with substantially similar chirality. The system provides a resonant frequency, keyed to a desired radial breathing mode linked to the desired chirality, that causes a template of catalysts particles or nanotubes to oscillate at the provided resonant frequency, so as to stimulate growing nanotubes to oscillate at a corresponding resonant frequency. This resonant frequency can be a result of a high frequency field or the natural heat radiation generated by the system.
