AN STM OBSERVATION OF ADSORPTION OF CuPc ON THE Si(100) SURFACE WITH Bi-LINE STRUCTURES

We report the reaction dynamics of the Bi-line structure (BLS) with copper-phthalocyanine (CuPc)molecules as well as hydrogen and Ag atoms on Si(100) surfaces observed by scanning tunnelingmicroscopy. Co-adsorption of hydrogen and Ag on the Si(100) surface with BLSs brought aboutagglomeration of Ag atoms on the Si terrace. When CuPc molecules were deposited on the Si(100)surface with BLSs at room temperature, domains with c(4×4) periodicity appeared in the terracesnear the BLS. When the surface was annealed at 200—400◦C, the area of the c(4×4) domain wasincreased. The CuPc molecules, adsorbed on BLS, were possibly dissociated by catalytic reaction ofBi atoms
