The excess volume associated with grain boundaries is one of the primary factors driving defect segregation and diffusion which controls electronic, mechanical chemical properties many polycrystalline materials. Experimental measurements boundary fcc metals Cu Ni have shown a difference over 40%. in lattice constant between only 3%, therefore this substantial currently lacking explanation. In article we employ high throughput computational approach to determine atomic structure, formation...
Abstract Polycrystalline metal oxides find diverse applications in areas such as nanoelectronics, photovoltaics and catalysis. Although grain boundary defects are ubiquitous their structure electronic properties very poorly understood since it is extremely challenging to probe the of buried interfaces directly. In this paper we combine novel plan-view high-resolution transmission electron microscopy first principles calculations provide atomic level understanding boundaries barrier layer a...
Magnetic tunnel junctions employing FeCoB as the ferromagnet and MgO a spacer layer exhibit high performance are attractive for magnetic random access memory applications. Upon postdeposition annealing, B is observed to diffuse out of layers inducing crystallization FeCo. It known that large proportion escapes into adjacent tantalum underlayer. While diffusion bulk be unfavorable, it possible could grain boundaries (GBs) in polycrystalline layer, affecting its electronic properties. In this...
There are several methods in which grain boundaries can be made for modelling, but most produce planar (flat) grains. In this study, we investigated the difference materials properties between polycrystalline systems comprised of and curved boundaries. Several structural mechanical both were determined. For with boundaries, it was found that elastic moduli all larger magnitude, excess volumes comparable, plastic smaller. addition, a tracking algorithm used to determine differences numbers...
