Abstract: We report the reaction dynamics of theBi-line structure (BLS) with copper-phthalocyanine(CuPc)molecules as well as hydrogen andAgatoms onSi(100)surfaces observed by scanning tunneling microscopy. Co-adsorption of hydrogen andAgon theSi(100)surface with BLSs brought about agglomeration ofAgatoms on theSiterrace. WhenCuPcmolecules were deposited on theSi(100)surface with BLSs at room temperature, domains with c(4 × 4) periodicity appeared in the terraces near the BLS. When the surface was annealed at 200°C–400°C, the area of the c(4 × 4) domain was increased. TheCuPcmolecules, adsorbed on BLS, were possibly dissociated by catalytic reaction ofBiatoms.
