AbstractThe orientation and packing arrangement of thiophene molecules on a well-defined Au(1 1 1) surface in 0.1 M HClO4 solution have been investigated as a function of applied potentials by in situ scanning tunneling microscopy (STM) and electrochemical method. Thiophene molecules are found to form highly ordered adlayers in the double layer region. High-resolution STM images reveal different adlayer structures. Thiophene molecules take flat-lying and vertical orientation at 0.3 and 0.6 V, respectively. Compared with the results of electrochemical measurement, we concluded that the phase transition of thiophene on Au(1 1 1) occurs as the potential is changed between 0.1 and 0.65 V.
