      abstract     = {The initial stage of the adsorption of octithiophene (8T)
                      molecules on a Cu(111) surface is investigated using a
                      scanning tunneling microscope at room temperature. We find a
                      characteristic molecular chain structure of 8T molecules on
                      a terrace of the Cu(111) surface, which has not been
                      reported so far for adsorption of oligothiophene molecules
                      on metal surfaces. Up to the adsorption of 0.26 monolayer
                      (ML), 81 molecules in the molecular chain align with their
                      long axis parallel to the Cu < 11-2 > direction. With
                      increasing coverage, there appear 8T molecules that align
                      with their long axis parallel to the Cu < 110 > direction.
                      The appearance of different molecular orientations is
                      understood by the decrease of the number of the adsorption
                      sites for extending the molecular chains. Fragments of 8T
                      molecules, such as single thiophene molecules, are also
                      observed in this work. They are trapped only at the step
                      edges of the Cu(111) surface at the beginning and later
                      trapped in a small Cu(111) region surrounded by 8T
                      molecules. (C) 2011 Elsevier B.V. All rights reserved.},
