Grain boundary structures of atomic layer deposited
Grain boundary plays an important role in determining the physical properties and chemical stability of the materials. In particular, the structures of grain boundaries in atomic layer deposited TiN film may be one of the main factors to dominate the reliability and performance of ULSI devices with multilayer structure of Cu-based interconnects. In this work, the characteristics of grain bounda...
متن کاملIdentification of Grain Boundary Contours at Atomic Scale
Nowadays image acquisition in materials science allows the resolution of grains at atomic scale. Grains are material regions with different lattice orientation which are typically not in equilibrium. At the same time, new microscopic simulation tools allow to study the dynamics of such grain structures. Single atoms are resolved in the experimental and in the simulation results. A qualitative s...
متن کاملAtomic-scale quantification of grain boundary segregation in nanocrystalline material.
Grain boundary segregation leads to nanoscale chemical variations that can alter a material's performance by orders of magnitude (e.g., embrittlement). To understand this phenomenon, a large number of grain boundaries must be characterized in terms of both their five crystallographic interface parameters and their atomic-scale chemical composition. We demonstrate how this can be achieved using ...

متن کاملShear-coupled grain boundary migration assisted by unusual atomic shuffling
Shear-coupled grain boundary (GB) migration can be an efficacious mechanism to accommodate plastic deformation when the grain size of polycrystalline materials goes small. Nevertheless, how this kind of GB motion comes into play at the atomic level has not been fully revealed. Here, we have investigated the shear-coupled migration (SCM) of typical [100] group symmetrical tilt GBs in bcc W using...
