GRAIN BOUNDARIES AND ANTIPHASE BOUNDARIES IN GaAs
Le Journal de Physique Colloques, 1988 Bicrystals of GaAs with a predetermined orientation relationships between the grains have been produced by growing GaAs epilayers on substrates cut from Czochralski-grown germanium bicrystals. Grain boundaries have also been generated in GaAs epilayers grown on (110) Ge substrate.

Dislocation‐Mediated Thermoelectric Performance and Mechanical Behavior
Advanced Engineering Materials, EarlyView.Dislocations can scatter phonons to reduce thermal conductivity, thereby enhance thermoelectric performance. However, dislocations also impact mechanical properties, leading to increased brittleness and altered plasticity. It is essential to clarify the complex relationship between dislocations, thermal transport, and mechanical stability to achieve a ...

Special Grain Boundaries in Ultrafine-Grained Tungsten
Nanoscale Research Letters, 2016 Field ion microscopy and computer simulation were used for the study of an atomic structure high-angle grain boundary in hard-drawn ultrafine-grained tungsten wire. These boundaries with special misorientations are beyond the scope of the coincident site lattice model.
