Ionic liquid-mediated epitaxy of high-quality C60 crystallites in a vacuum

Author affiliations

Abstract

Ionic liquid-mediated vacuum deposition was demonstrated as a novel growth technique for high-quality C60 crystallites. In this process the ionic liquid worked as a solvent, i.e. the gas phase C60 precursors were continuously fed into the ionic liquid on a substrate in a vacuum chamber, from which the nucleation and the subsequent growth of C60 crystallites proceeded. The impact of varying the substrate on the growth behaviour was intensively examined in terms of not only the lattice-mismatch between C60 and the substrates, but also the wetting behavior of the ionic liquid on the substrates. This led to a significant improvement of the C60 crystallinity and epitaxial growth was successfully found on certain substrates. In particular, molecularly smooth and thick C60 hexagonal-shaped crystallites epitaxially grew on a MoS2 substrate, the average size of which reached as large as 10 μm.
