Researchers used AI-guided electron microscopy to map atomic-level point defects in 3D within ultrathin MXene layers, ...

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.

Emergence of anti-hyperuniform defect organization in active nematics. At high activity (left), topological defects are distributed nearly uniformly throughout the system. Reducing activity toward a ...

Order doesn’t always form perfectly—and those imperfections can be surprisingly powerful. In materials like liquid crystals, tiny “defects” emerge when symmetry breaks, shaping everything from cosmic ...

In biology, defects are generally bad. But in materials science, defects can be intentionally tuned to give materials useful new properties. Today, atomic-scale defects are carefully introduced during ...
