From dewetting to wetting molecular layers: C60 on CaCO3(10
4) as a case study
Abstract
We report the formation of extended molecular layers of C60 molecules on a dielectric surface at room temperature. In sharp contrast to previous C60 4) surface as a substrate. Non-contact
4) in the [01
0] direction, while a lattice mismatch along the [
61] direction results in a large-scale moiré modulation. Overall, a (2 × 15) wetting layer is obtained. The distinct difference observed microscopically upon C60
4) compared to other dielectric surfaces is explained by a macroscopic picture based on surface energies. Our example demonstrates that this simple surface-energy based approach can provide a valuable estimate for choosing molecule–insulator systems suitable for molecular
