Carbon nanotubes for nanoscale electronics and nanoelectromechanical systems.

摘要

This dissertation describes our experimental studies of the electronic and mechanical properties of carbon nanotubes. To obtain repeatable results from these very small structures, we have fabricated electronic and electromechanical devices which can then be tested in controlled environments. We correlate measurements performed on these devices with nanotube structure through simultaneous high resolution electron microscopy. Our measurements reveal valuable insights into both the nature of electronic conduction in multiwalled carbon nanotubes and their dynamic, mechanical bearing structure. Finally, by studying the fabrication processes themselves, we have developed numerous techniques to manipulate and modify individual carbon nanotubes, including methods to attach, clean, cut, shrink, peel, and place carbon nanotubes in specific locations and orientations.
