We report low-temperature transport measurements through molecules of Gd metallofullerenes between superconducting suspended electrodes. The presence and number of molecules in the 2-nm-wide gap between electrodes was determined by high resolution transmission electron microscopy. We find that a junction containing a single metallofullerene dimer between superconducting electrodes displays signs of proximityinduced superconductivity. In contrast, no proximity effect develops in junctions containing a larger cluster of metallofullerenes. These results can be understood by taking into account multiple Andreev reflections, and the spin states of the Gd atoms.

A high-performance pentacene organic-TFT backplane with a solution-processed novel poly(4-vinylphenol)-based dielectric and a solution-processed organo-silver electrode/wire has been developed below 150°C. The all-organic-TFT backplane has been successfully applied to drive a QQVGA active-matrix (AM) polymer-dispersed (PD) LCD with a resolution of 79 dpi and a display size of 2.5 inches.
