Nanoscale Structure Formation on Sputter Eroded Surface
Experimental results on ion sputtered surfaces, covering amorphous and crystalline materials (SiO2 [1]), and both metals (Ag [2]) and semiconductors (Ge [3], Si [4,5]), have motivated extensive theoretical work aiming to uncover the mechanism responsible for ripple formation and kinetic roughening. A particularly successful model has been proposed by Bradley and Harper (BH) [6], in which the he...
متن کاملA Study of Extended Defects in Surface Damaged Crystals
We have analyzed by transmission electron microscopy silicon and GaAs crystals polished with sandpapers of different grain size. The surface damage induced a crystal permanent convex curvature with a radius of the order of a few meters. The curvature is due to a compressive strain generated in the damaged zone of the sample. Contrary to what was reported in the literature, the only defects dete...
متن کاملChemistry of mass-selected Au clusters deposited on sputter-damaged HOPG surfaces : The unique properties of Au8 clusters
Mass-selected Au clusters consisting of less than 10 atoms were deposited on sputter-damaged HOPG surfaces. Oxidation and reduction of the Au clusters were studied using X-ray photoelectron spectroscopy. Only Au8 can be significantly oxidized by oxygen and reduced by CO, and the result is different from those for Au clusters deposited on silica. The chemical properties of mass-selected clusters...
متن کاملRestructuring of an Ir(210) electrode surface by potential cycling
This study addresses the electrochemical surface faceting and restructuring of Ir(210) single crystal electrodes. Cyclic voltammetry measurements and in situ scanning tunnelling microscopy are used to probe structural changes and variations in the electrochemical behaviour after potential cycling of Ir(210) in 0.1 M H2SO4. Faceted structures are obtained electrochemically as a function of time ...
