摘要

After its discovery in 1991, carbon nanotube has rapidly emerged as the most promising candidate for molecular electronics due to its quasi-one dimensional structure and the unique characterization of its electronic structure in terms of two simple geometric indices. Besides its huge technological potential, carbon nanotube also serves as the artificial laboratory in which one-dimensional transport can be investigated, similar to the semiconductor quantum wire. However, unlike its semiconductor cousin where transport is mostly ballistic, the study of transport in carbon nanotube has been distressed by the difficulty of making low resistance contact to the measuring electrodes. The high resistances reported in various two- and three-terminal measurements have led Tersoff (and also independently by one of the authors) to suggest that wavevector conservation at the metal-carbon nanotube contact may play an important role in explaining the high contact resistance. The complexity and importance of the metal-carbon nanotube interface makes it an immediate challenge to both theorists and experimentalists.
