Cherepanov V. Investigations of ultrathin organic films by means of scanning probe microscopy

The thesis deals with the investigations of structure and electronic/ electroluminescent properties of ultrathin organic films by means of scanning tunneling and atomic force microscopy. A terbium complex and its organometallic nanocomposites, carbon nanotubes, n octane acid, oxyphenyl-naphthalimide were investigated. It was shown that thermal dispersion of nanotubes causes the changes of current-induced electron and photon emission. It has been shown that highly ordered chemisorbed monolayers of saturated organic acids can be obtained on reconstructed Au(111) surface. Using STS-method the diode-like I(V)-characteristics have been experimentally observed for oxyphenyl-naphthalimide films. A part of the work is devoted to development of scanning probe microscopy methods. In particular, it has been demonstrated that AFM can be used for fabrication of nanogaps.
