Atomic configurations at InAs partial dislocation cores associated with Z-shape faulted dipoles

The atomic arrangements of two types of InAs dislocation cores associated by a Z-shape faulted dipole are observed directly by aberration-corrected high-angle annular-dark-field imaging. Single unpaired columns of different atoms in a matrix of dumbbells are clearly resolved, with observable variations of bonding lengths due to excess Coulomb force from bare ions at the dislocation core. The co...

Structure and Climb of Faulted Dipoles in GaAs

Z-shape faulted dipoles in deformed GaAs were investigated by using high resolution electron microscopy. There is no difference in the core structure of the a and b dislocations of stair-rod and 90 Shockley partials, nor in the dissociated stacking fault width. The central stacking fault is found to generate large local atomic displacements and exhibits a different structure from that of the in...

Shape-consistent Relativistic Effective Potentials of Small Atomic Cores

Relativistic effective core potential (RECP) models for electronic structure calculations of atoms, molecules, clusters, and solids, satisfying the shape-consistence (norm conservation) requirement are presented and analyzed. To attain a high accuracy of predicting various physical properties with field-independent RECP models, both valence and subvalence (outer-core) electronic shells should b...

Formation of dislocation dipoles in irradiated graphite

Recently, we have proposed a dislocation dipole accumulation model to explain the irradiation-induced amorphization of graphite. However, the structure of dislocation dipole in the hexagonal networks is still an open question at the atomic-level. In this paper, we propose a possible formation process of the dislocation dipole. © 2001 Elsevier Science. All rights reserved

Characterizing faulted dipoles in TiAl with electron microscopy and computed image simulations

The low temperature deformation microstructure of TiAl is dominated by the presence of stacking fault dipoles [I]. Two different faulted dipole geometries have been proposed in the literature [2,3], and the existence of both types of faulted dipoles have been verified in the present study with comparisons to computer simulated images. These comparisons suggest that extrinsic stacking faults in ...
