An atomically flat pentacene monomolecular layer remarkably improved the crystallinity of C60 films, thus enhancing the field-effect mobilities in C60 transistors (FETs) (see figure). They showed a four to five times better performance over devices with C60 films grown without a pentacene buffer. Molecular-wetting-controlled substrates can thus offer a general solution to the fabrication of high-performance crystalline organic devices.
