Abstract
At submonolayer coverages Cu-phthalocyanine (CuPc) induces faceting of misoriented Ag(110) into three coexisting orientational phases. CuPc- decorated kinks precipitate into an azimuthally rotated facet, while t he interaction of CuPc with the remaining kink-depleted steps causes s tep bunching in apolar transition. Local deviations from the CuPc-indu ced equilibrium surface morphology are caused by kinetic constraints a ttributed to the dominating interaction with kinks. At monolayer cover age a rigid molecular superstructure prevents large scale mass transpo rt and allows only for microfaceting.
