PT(111)We report a study of the fluctuations exhibited by step edges on clean Au(1 1 1), using low energy electron microscopy. The research yields values for the surface mass diffusion coefficient D s and the orientation-dependent step stiffness β ( θ ) through the temperature range 900...
From the spatial variation of the barrier height, sharp enlargement and reduction of the surface potential are obtained at the upper and lower step edges, respectively, which are characterized as the Smoluchowski effect. We also observe the potential with oscillatory decay away from the step, known...
(111), which is modified from vanadyl phthalocyanine (VOPc) by replacing the inert phthalocyanine ligand with a reactive thiadiazole moiety. The magnetic properties of the molecules are examined by observing the Kondo resonance caused by the screening of an isolated spin by conduction electrons using...
For a small subset of sources from herbaria, providing a text description of taxa, we used regular expressions in R to extract measurements of traits from the text. A variety of expressions were developed to extract height, leaf/seed dimensions and growth form. Error checking was completed on ...
Detailed analysis of z-V spectroscopy (ramping the tunneling bias V while keeping the tunneling current constant) provides information on the bias dependent apparent height of a single 4MPy/Au(111) as well as on the local density of states (LDOS) of single and chain 4MPy molecules in ...
The simulated height difference between NHCs at the step edge and NHCs in the surface bound lattice (115 pm) and an isolated, surface-bound NHC (219 pm) are in good agreement with experiment (220 ± 10 pm). c Array of surface- bound NHCs on Au(111) (50 pA, 400 mV, 30.0 × 30.0...
However, SAM-modified Au(111) recovers catalytic activity for the HPOR already after a single metallization step fabricating Pt islands on-top. Hydrogen peroxide (HP) may then either react at the (non-metallic) Pt nanoislands or on reactivated Au sites, made accessible by structural changes of...
FORMATION OF AU NANOSTRUCTURES AT STEP EDGES OF PD3FE(111) AND THEIR ROLE IN O2 REDUCTIONThe sluggish kinetics of the electrochemical reduction of molecular oxygen (ORR) in polymer electrolyte membrane fuel cells (PEMFCs) requires continued search for proper catalysts. The cost and stability of ...
Step-induced slanted perpendicular magnetic anisotropy in 4°-miscut Si(111)/Cu/Au/Co/Au system 来自 掌桥科研 喜欢 0 阅读量: 18 作者:CY You,S Lee,S Park,CM Falco 摘要: We performed magneto-optic Kerr effect and Brillouin light-scattering measurements on a 4°-miscut Si(111)/Cu/Au(2ML...
However, upon exposure to the flux of elemental B at elevated temperatures, the surface morphology changes drastically: a very regular pattern of densely packed equilateral triangles starts to emerge on the (111) terraces (Fig. 1a). The arrays of these triangles usually propagate from the step ...
