In March 2006, IBM (White Plains, N.Y.) announced that its researchers had built the first complete IC around a single carbon nanotube (CNT) molecule.1,2 The ring oscillator circuit was built using standard semiconductor processes and a single molecule as the base for all components in the circuit, rather than linking together individually constructed components. This approach simplifies manufacturing and provides a consistency needed to more thoroughly test and adjust the nanotube material. By integrating the complete circuit around a single nanotube (Figure), the IBM team observed circuit speeds nearly a million times faster than ...
