Reference plane for the electronic states in thin films on stepped surfaces

ABSTRACTIn situ Raman scattering, UPS and HREELS measurements have been used to study the fcc to orthorhombic phase transition in RbC60 thin films. Large changes in the Raman spectra are interpreted in terms of increased interfullerene coupling in the orthorhombic phase. However, the data do not support the proposed polymer model for this phase. Photoemission measurements indicate only small differences in the electronic states between the two phases in contrast with photopolymerized C60 where additional states are observed. Low energy metallic-like excitations and screening of intramolecular vibrations are observed in HREELS.

ABSTRACTThe surface electronic structures of conjugated regio regular and regio random poly (3- hexylthiophene) (rr-P3HT and rra-P3HT) thin films were studied by near edge X-ray absorption fine structure spectroscopy, ultraviolet photoelectron spectroscopy and Penning ionization electron spectroscopy (PIES). The distribution of the surface electronic states was controlled on rr-P3HT and rra-P3HT thin films with different molecular ordering by varying the coating process and PIES was adopted to observe the electronic states existing outside the surface.

Oscillatory Structure

By following the theory of quantum transport and rough surface scattering developed by Tešanović et al., we present here a microscopic calculation of electronic conductivity in metallic thin wires. The rising of conductivity with the increase of the radius of a wire has a more complicated oscillatory structure than that found in thin films. The scattering on the rough surface in wires can lead both to the violation of Mattheissen's rule and to the localization of electronic states.
