| Research Abstract |
The epitaxial growth of single-crystalline-like organic multilayer films on selected metal surfaces, chosen to provide either weak or strong interactions at the hybrid interface, has been studied. In particular, while molecules containing heteroatoms form site-specific covalent bonds, the growth of oligoacenes on the Cu(110) surface is characterized by extended interfacial states and a flat molecular orientation in the first layer. On the contrary, for surfaces providing weak interactions like Bi(001) and silicene, both standing and flat orientations occur and are governed by the specific lattice-matching conditions for various crystallographic planes of the thin film crystals. The results provide a detailed understanding of the influence of the substrate beyond the widely studied first layer in achieving epitaxial growth and uniaxial alignment of the grains.
