Abstract

Fullerene C60 was purified and imaged utilizing scanning tunneling microscopy (STM) in a constant current mode. By fixing the fullerenes on the substrate (“frozen state” — no movement or rotation), direct imaging of C60 with atomic resolution was possible, showing pentagon and hexagon carbon rings of C60. A high voltage STM pulse of C60 appears to have created a defect resulting in C58 which can dimerize to C116. C116 has potential utility as a molecular switching device.
