Organic Materials: From Insulator to Superconductor
(Click here
for a higher-resolution image.)
What lies behind the superconductivity of organic materials, such as polyacenes
(anthracene) and fullerenes
(C60)? Professor Philip
Phillips believes that a clue might be provided by the electron-phonon coupling—the
"glue" that binds electrons into superconducting Cooper pairs. The electron-phonon
coupling constant for a series of organic semiconductors is shown as a function
of the number of p-electrons associated with their
carbon rings.

superconductor," Nature 406, 687–688 (August 17, 2000).
