An iterative experimental-theoretical technique was developed for the identification of defects in nanoscale materials. The atomic structure of defects were analyzed using scanning tunneling microscopy and spectroscopy. The defects, which were responsible for the electronic properties of carbon nanotube intramolecular junction, were also identified using the method. THe method was also to solve problems such as, the influence of defects on transport, exciton lifetimes in quantum dots, and mechanical properties of nanotubes, nanowires, and nanocrystals.
