Brun expansions of stepped surfaces
Dual maps have been introduced as a generalization to higher dimensions of word substitutions and free group morphisms. In this paper, we study the action of these dual maps on particular discrete planes and surfaces – namely stepped planes and stepped surfaces. We show that dual maps can be seen as discretizations of toral automorphisms. We then provide a connection between stepped planes and ...
متن کاملUncommon dislocation processes at the incipient plasticity of stepped gold surfaces.
Gold vicinal surfaces (788), with a high density of steps, along with (111) flat surfaces taken as a reference, have been nanoindented and their resulting penetration curves and related defect structure comparatively analyzed by AFM and atomistic simulations. Stepped surfaces are shown to yield at smaller loads than (111) ones in agreement with calculations of the critical resolved shear stress...
متن کاملA COMPARISON OF NO INTERACTION WITH STEPPED Pt AND Ru FIELD EMITTER SURFACES
The adsorption and the catalytic decomposition of NO on Pt and P.u field emitter surfaces has been studied by pulsed field desorption mass spectrometry (PFDMS). A molecular adsorption of NO vas found on stepped Pt(lll) and (001) surfaces in the absence of electrostatic fields. From the temperature dependence of the nean lifetimes before thermal desorption an activation energy Ed= 153 kJ/ral and...
متن کاملOne-pot fabrication of novel cuboctahedral Cu2O crystals enclosed by anisotropic surfaces with enhancing catalytic performance.
For the first time, one-pot solution-phase selective-etching to create cuboctahedral Cu2O crystals enclosed by both stepped {111} surfaces and smooth {100} surfaces has been demonstrated. Investigation of photocatalytic performances indicates that the stepped cuboctahedral Cu2O crystals have higher photocatalytic activities than those of the common smooth ones.
متن کاملBromine atom diffusion on stepped and kinked copper surfaces
The rates of Br atom diffusion on several single crystalline Cu surfaces have been studied because of the potential impact of Br diffusion on the selectivity of alkyl bromide surface chemistry on Cu. Density functional theory (DFT) has been used to study the diffusion of isolated bromine atoms on a flat Cu surface, Cu(111), two Cu surfaces with straight steps, Cu(221) and Cu(533), and two kinke...
