Abstract
  • We investigated the electronic, morphological and transport properties of 6,13-pentacenequinone thin films grown by vacuum thermal evaporation gram on silicon oxide (native and thermally grown) substrates at room temperature using X-ray photoemission spectroscopy.. atomic force microscopy and in situ transport measurements. The chemical properties of the molecule have been characterized by high resolution C1s, O1s and Valence Band X-ray photoemission as a function of the thickness and the photoemission peaks were interpreted on the basis of density functional theory calculations. The photoemission analysis of the above mentioned regions reveals characteristic features (namely a double peak on C Is due to the six inequivalent carbon atoms, a single peak on O1s at binding energy of 531.3 eV and a feature centered at 3.7 eV assigned to a convolution of the highest occupied molecular orbitals). Atomic force microscopy measurements show an initial amorphous wetting layer with a subsequent island growth in two different crystalline phases, namely the bulk crystal phase and a metastable substrate induced phase. Finally, electrical measurements evidence the insulating character of 6,13-pentacenequinone films with a resistivity p >= 5 x 10(6) Omega m. (C) 2007 Elsevier B.V. All rights reserved. (literal)
