摘要：

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 the interaction of CuPc with the remaining kink-depleted steps causes step bunching in apolar transition. Local deviations from the CuPc-induced equilibrium surface morphology are caused by kinetic constraints attributed to the dominating interaction with kinks. At monolayer coverage a rigid molecular superstructure prevents large scale mass transport and allows only for microfaceting.
