| Abstract
| - Deposition of perylene on copper substrates leads to the formation of various ordered thin film phases and exhibits, especially on Cu(110), a long-range ordered stripe structure which is accompanied by an enhanced step density of the substrate at elevated temperatures.
- The growth of ultrathin perylene films on Cu(110) and Cu(100) surfaces has been studied by meansof He atom scattering, low-energy electron diffraction, scanning tunneling microscopy, thermal desorptionspectroscopy, and X-ray photoelectron spectroscopy with a special emphasis on the interface structure.In addition to several ordered submonolayer phases, two distinctly different monolayer structures werefound at substrate temperatures below 380 K and at about 450 K on Cu(110). The rather open saturationstructure formed at elevated temperatures reveals an enhanced density of substrate steps, which indicatesan adsorption-induced modification of the Cu(110) surface. In contrast to that, on Cu(100), only a close-packed c(8 × 4) monolayer structure is formed without any less-dense-packed structures.
