Strain-Relief Patterns and Kagome Lattice in Self-Assembled C60 Thin Films Grown on Cd(0001)

We report an ultra-high vacuum low-temperature scanning tunneling microscopy (STM) study of the C60 monolayer grown on Cd(0001). Individual C60 molecules adsorbed on Cd(0001) may exhibit a bright or dim contrast in STM images. When deposited at low temperatures close to 100 K, C60 thin films present a curved structure to release strain due to dominant molecule–substrate interactions. Moreover, edge dislocation appears when two different wavy structures encounter each other, which has seldomly been observed in molecular self-assembly. When growth temperature rose, we found two forms of symmetric kagome lattice superstructures, 2 × 2 and 4 × 4, at room temperature (RT) and 310 K, respectively. The results provide new insight into the growth behavior of C60 films.

Structure and conductive properties of C60 films and fullerene-containing materials deposited using aromatic and non-aromatic solvents

Films of fullerenes and fullerene-containing materials have been synthesized from their solutions of various volumes in aromatic and non-aromatic solvents. The photographs and the sizes of the resulting microstructures have been presented. The comparison of IR spectra has been given. Specific conductivity values have been considered.

The results of using N-isoamylisatin 4-methylphenylhydrazone to optimize fullerene-based heterostructures have been presented. The technique of obtaining, microscopy, as well as the results of IR spectroscopy and the study of the electrophysical properties of thin films of this hydrazone together with fullerene C60 have been described. The addition of the considered organic matter to fullerene films made it possible to increase the photoconductivity by 2 orders of magnitude compared to C60 films. The obtained thin-film structures have rectifying light-current-voltage characteristics.
