Self-assembly of C<sub>60</sub> on a ZnTPP/Fe(001)–<i>p</i>(1 × 1)O substrate: observation of a quasi-freestanding C<sub>60</sub> monolayer
Abstract
<jats:p>Fullerene (C<jats:sub>60</jats:sub>) has been deposited in ultrahigh vacuum on top of a zinc tetraphenylporphyrin (ZnTPP) monolayer self-assembled on a Fe(001)–<jats:italic>p</jats:italic>(1 × 1)O substrate. The nanoscale morphology and the electronic properties of the C<jats:sub>60</jats:sub>/ZnTPP/Fe(001)–<jats:italic>p</jats:italic>(1 × 1)O heterostructure have been investigated by scanning tunneling microscopy/spectroscopy and ultraviolet photoemission spectroscopy. C<jats:sub>60</jats:sub> nucleates compact and well-ordered hexagonal domains on top of the ZnTPP buffer layer, suggesting a high surface diffusivity of C<jats:sub>60</jats:sub> and a weak coupling between the overlayer and the substrate. Accordingly, work function measurements reveal a negligible charge transfer at the C<jats:sub>60</jats:sub>/ZnTPP interface. Finally, the difference between the energy of the lowest unoccupied molecular orbital (LUMO) and that of the highest occupied molecular orbital (HOMO) measured on C<jats:sub>60</jats:sub> is about 3.75 eV, a value remarkably higher than those found in fullerene films stabilized directly on metal surfaces. Our results unveil a model system that could be useful in applications in which a quasi-freestanding monolayer of C<jats:sub>60</jats:sub> interfaced with a metallic electrode is required.</jats:p>
