Abstract
Within the proposed research program we intend to: (i) investigate the interfaces of complex fluids, like liquid crystals and other organic macromolecules, on solid surfaces. We shall use Atomic Force Microscopy and Force Spectroscopy, Scanning Tunneling Microscopy, linear optical ellipsometry and nonlinear optics to investigate the nature of forces that are responsible for ordering and self-organization of complex fluids. We shall analyze viscoelastic properties and structure of interfaces in the vicinity of phase transitions using force spectroscopy in systems that exhibit a spontaneous breaking of either translational or orientational symmetry. We shall also investigate the role of Casimir interaction in the vicinity of phase transitions in liquid crystals. (ii) The second part of research program comprises investigations of a series of transition-metal di-, tri- and terachalcogenides. These systems are of interest due to their specific crystallographic and physical properties, like e.g. the appearance of spontaneous superstructures and charge density waves. Using scanning tunneling microscopy, transmission electron microscopy, low-energy electron diffraction combined with Auger spectroscopy and metal deposition by means of a Knudsen source, we shall study surface structures, which are in metals often different from the corresponding bulk structures. We shall also study nucleation, growth processes and possibly manipulation at the atomic level, which represent the basis for a controlled fabrication of metallic nanostructures. As part of the program we also intend to modernize and upgrade the existing UHV-STM system. (iii) The third part of the program represents studies of synthesis, structural and physical characterization of inorganic micro and nanotubes with special emphasis on their electrical, mechanical and optical properties. A significant part of research will also be directed into investigations of nanoparticles and metal oxides for their potential application in industry.
