Atomic vacancies are a type of point defect in a crystal lattice where one or more atoms are absent from their regular lattice positions. Although they might seem like simple imperfections, these ...

Researchers and industries have been using transmission electron microscopy (TEM) to study semiconductors' stacking and dislocation faults. This article considers the analysis of crystal structures.

Quantum engineers have spent years trying to tame the fragility of qubits, only to be thwarted by the tiniest imperfections in the materials they use. Now a new line of research flips that problem on ...

Researchers observed the phase transition of topological defects formed by liquid crystal (LC) materials for the first time. The phase transition of topological defects can be difficult to understand ...
