Metallic behaviour of carrier-polarized C${}_{60}$ molecular layers: Experiment and Theory

Z. H. Lu, C. C. Lo, C. J. Huang +2

Although C${}_{60}$ is a molecular crystal with a bandgap E${}_g$ of ~2.5 eV, we show that E${}_g$ is strongly affected by injected charge. In sharp contrast to the Coulomb blockade typi…
