      abstract     = {Adsorption and electronic structure of octithiophene (8T)
                      molecules on Cu(111) and Au(111) surfaces are investigated
                      using scanning tunneling microscopy (STM) and spectroscopy
                      (STS) at room temperature. We find a large difference in
                      adsorption behavior of 8T molecules on the two surfaces. At
                      the initial stage of adsorption, 8T molecules are stabilized
                      in the form of molecular chain on a terrace of Cu(111),
                      whereas neither such chain structure nor isolated 8T
                      molecules have been observed on a terrace of Au(111). By
                      increasing the amount of adsorbed molecules, a disordered
                      monolayer film is formed on Cu(111) while a well-ordered
                      monolayer film is formed on Au(111). From the spectroscopic
                      investigations using bias-dependent STM images and STS
                      spectra and by comparing the data with theoretical
                      calculations, it is found that the electronic property of 8T
                      molecules in the molecular chain on Cu(111) is different
                      from that of a free-standing 8T molecule while that in the
                      monolayer film on Au(111) keeps original character of the
                      free-standing 8T molecule. The present study shows that
                      adsorption of 8T molecules on Cu(111) results in a formation
                      of adsorption-induced states near the Fermi level.},
