This schematic illustration shows the generation of dislocation arrays during the liquid-phase compaction process. The Te liquid (red) between the Bi0.5Sb1.5Te3 grains flows out during the compacting ...

We might imagine crystals to be perfect structures, but they are, in fact, often plagued with "defects." Curiously enough, such defects often appear due to atoms undergoing reorganization to lower the ...

Dislocation arrays at interfaces in PbZrO3 thin films spontaneously produce ordered "antihedgehog" polar domain lattices through coupled electrostrictive and flexoelectric effects. Polarization ...
