This paper focuses on an area of nanoelectronics to which chemists have been making substantial contributions in the past five to ten years. It discusses what the chemical challenges are and what the state of the art is in the field of nano-lT. 

One can use molecules to augment the capabilities of the cross wires. It is not difficult to make small structures down to 60 nm, but it is difficult to bring them close together, so density becomes the most challenging synthetic capability.

David R. Rea of E. I. du Pont de Nemours and Company prepared the presentation summaries of Richard M. Gross, Allen Clamen, Elsa Reichmanis, and Lawrence H. Dubois. The summaries for the presentation of Mary L. Good, James R. Heath, Francis A. Via, and Kenneth A. Pickar were prepared by Ned D. Heindel. Andrew Kaldor wrote the summaries of the presentations by Venkat Venkatasubramanian, Michael Schrage, and Richard K. Koehn. 

James R. Heath, of the University of California, Los Angeles, discussed molecular electronics as a prototypical hot topic, exemplifying the kind of early-stage technology that has extraordinary commercial potential but lacks sufficient certainty to attract development funding. He presented a vision for developing commercially valuable nano-level computers that was in sharp contrast to the reality of limited venture capital or governmental aid available to develop the field.

Another class of carbon allotropes was discovered in 1985 by Harold W. Kroto, James R. Heath, Sean O Brien, Robert Curl, and Richard Smalley. Soccer-ball-shaped spheres of 60 carbon atoms with formulas like Cgg and C were found in carbon soot and later recognized to be ubiquitous in interstellar clouds. Cg is recognized as the most perfectly spherical known molecule. Because the arrangements of the carbon atoms resemble the architecture of geodesic domes, which were invented by Richard Buckminster Fuller, this class of carbon allotropes came to be cdXXed fullerenes. Kroto, Curl, and Smalley shared the 1996 Nobel Prize in chemistry for this discovery. 

In September 1985 British chemist Harold Kroto (Figure 4 65) of the University of Sussex collaborated with Americans Richard E. Smalley, Robert F. Curl, James R. Heath and Sean C. O Brien at Rice University in Houston, Texas in some experiments on graphite. Kroto had an interest in molecules found in interstellar space and had wanted to show that molecules containing long chains of carbon atoms could be formed under the conditions believed to be typical of the outer atmospheres of stars known as red giants. Smalley had developed a cluster beam apparatus which could vaporize small samples of solid graphite into carbon atoms which could be rapidly cooled and analysed.
