Transport properties of C 60 ultra-thin films

Abstract

We have grown the C 60 ultra-thin films on natural mica substrates aiming at nano-scale devices. Whereas, the appearance of the high temperature superconductivity in hole-induced C 60 bulk single crystal and CHBr 3 intercalated C 60 bulk by the field effect have attracted extensive attention. From the viewpoints of nano-scale devices and superconductivity, we grew single crystal thin films, those were grown on the buffer layer (5 nm thickness) of the C 60 ultra-thin films. We concluded that the optimized C 60 film was a single crystal with quite-thin thickness on the buffer layer for nano-scale devices and appearance of superconductivity.
