Modeling the Vibration of Defect-Bearing Carbon Nanotubes Using Reduced-Order Methods

Additional Information:

Flawless carbon nanotudes, due to their highly ordered structure, have the potential to possess very desirable mechanical, electrical, and thermal properties. The measured properties of actual nanotubes rarely live up to these predictions, though, because of the inevitable presence of defects. Not only do these defects alter the nanotubes' properties, but they change the way that nanotubes can be modeled and analyzed. This talk will focus on modeling carbon nanotudes with isotope, Stone-Wales, and multi-vacancy defects, and on methods of reducing the order of the resulting models in such a way that certain vibrational properties are preserved.
