... and above the critical potential. Some features experimentally observed for dealloying systems are then considered. The chapter concludes by briefly reviewing the proposed mechanisms for the formation of porous metals, namely ionization-redeposition mechanism, surface diffusion mechanism, volume diffusion...

... to be deposited can be evaporation, sputtering, arc erosion, laser ablation, or other evaporation sources. The energetic particles used for bombardment are usually ions of an inert or reactive gas. For every atom in a vapor cloud, there is a finite probability that it will ionize [ Hill 1986 ]. The magnitude...

... by of additional material such as the trench oxide, an amorphous layer from ion beam exposure, sample thickness variations resulting from uneven milling (‘curtain’ or ‘water-fall’ effect) or redeposition of various sputtered materials. The thickness of damaged amorphous layer can be reduced low energy (< 5keV...

... for additional growth ( Fig. 18.25 ). The metal ionizes at the surface, and then both the metal ions M 2+ and the electrons diffuse through the oxide layer to the oxygen surface. Electrons aid in forming the oxygen ion. The ions react near the oxygen surface to form the MO oxide. In this case, the rate...

The metal ionizes at the surface, and then both the metal ion (M ++ ) and the electrons diffuse through the oxide layer to the oxygen surface. Electrons aid in forming the oxygen ion.
