Elastic models of symmetrical Š001‹ and Š011‹ tilt grain boundaries in diamond
The disclination-structural units model ~DSUM!, which was previously applied to grain boundaries in metals and a limited number of structures in the diamond cubic lattice, is extended to treat more complicated metastable structures of ^001& and ^011& symmetric tilt boundaries in diamond. These structures are described in terms of flat and faceted disclination dipole walls and screw dislocation ...
متن کاملasymmetric tilt grain boundaries in fcc metals by atomistic simulations
The shear response of the 3 [1̄ 1 0]-tilt (1̄ 1̄ 5)/(1 1 1) and 9 [1̄ 1 0]-tilt (1 1 5)/(1 1 1) asymmetric tilt grain boundaries (GBs) in fcc metals Cu and Al has been studied by atomistic simulation methods with the embedded atom method interatomic potentials and with a bicrystal model. It is found that the structure of the GBs studied can be well described by the coincidence site lattice (CSL) th...
متن کاملThe Generalized Tilt Formula
A convex hull consmaction in Minkowski space defines a canonical cell decomposition for a cusped hyperbolic n-manifold. An algorithm to compute the canonical cell decomposition uses the concept of the 'tilt' of an n-simplex relative to each of its (n 1)-dimensional faces. An essential tool for computing tilts is the tilt theorem. The tilt theorem was previously known only in dimensions n < 3, a...
متن کاملInfluence of [0001] tilt grain boundaries on the destruction of the quantum Hall effect in graphene
The half-integer quantum Hall effect (QHE) is often suppressed in graphene grown by chemical vapor deposition on metals. The reason behind the suppression is unclear, and we hypothesize that it might be connected to extended defects in the material. In this paper we present results for the quantum Hall effect in graphene with [0001] tilt grain boundaries connecting opposite sides of Hall bar de...
متن کاملThe Multiple Roles of Small-Angle Tilt Grain Boundaries in Annihilating Radiation Damage in SiC
Lattice defects generated by radiation damage can diffuse to grain boundaries (GBs) and be annihilated at GBs. However, the precise role of GBs in annihilating the segregated defects remains unclear. Here, we employed multi-scale models to determine how interstitials are annihilated at small-angle tilt GBs (STGBs) in SiC. First of all, we found the pipe diffusion of interstitials in STGBs is sl...
