Pit initiation on passivated metal surfaces: crystallographic orientation and environmental effects
… of tin and zinc was found to be dependent on the crystallographic orientation of the surface in chloride solutions. For tin single crystals, the(111) face showed the lowest critical pitting potential among five differently oriented surfaces. The critical pitting potential of zinc single crystals …

Scanned pulsed laser annealing of Cu thin films
… is the dominant mechanism, and therefore the crystallographic orientation of the grains could influence reliability. Scanned laser annealing can, in principle, be used to develop test structures with extremely large grains which could be used to quantify the effects of grain boundary …

Chemo-elastic behavior of reconstructed Li-ion battery cathode particles with phase transformation: a numerical and analytical investigation
… of: i) phase transformation; ii) anisotropy and crystallographic orientation; iii) Li-composition inhomogeneity; iv) particle morphology and size; and v) composition-dependent chemical-expansion coefficient, [beta]. Diffusion-induced stresses (DIS) can be quite extreme with increasing particle …

Atom-by-Atom Substitution of Transition Metals in Gallium Arsenide and Visualization of Hole-Mediated Interactions
… Mn pairs as a function of relative position and orientation. Our experimental findings, which can be explained using tight-binding model calculations, reveal a strong dependence of ferromagnetic interaction on crystallographic orientation. This anisotropic interaction can potentially be exploited …

Structure-property relationships in strontium barium niobate relaxor ferroelectrics
… response was found to be strongly dependent on crystallographic orientation, in distinct comparison to the nearly orientation independent response found for Pb-based perovskite relaxors. The dielectric absorption of SBN was also found to be much stronger along the c-axis than along any other …

Integrated Growth and Process Technology for Atomically Thin Single Crystal Films
… problem is the control of the topographical and crystallographic texture of the catalyst. It is generally agreed in the literature that Cu(111) is the ideal growth catalyst to produce the highest quality graphene, yet there is significant difficulty in producing flat single crystal Cu at wafer …

Structure Evolution of Biaxially Aligned Thin Films Deposited by Sputtering
… films are polycrystalline thin films whereby the crystallographic orientation of the grains is aligned along two axes, i.e. perpendicular (out-of-plane) and parallel (in-plane) to the substrate. In the limit, all grains are perfectly aligned and the thin film bears likeness to single crystalline …
