Materials that emit and manipulate light are at the heart of technologies ranging from solar energy to advanced imaging systems. But even in well-studied materials, some fundamental behaviors remain ...

Perovskites are among the most extensively studied materials in modern materials science. Their often unique and exotic properties, which stem from perovskite's peculiar crystal structure, could find ...

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 ...

In crystals, defects are well-defined and crucial to their mechanical properties. In contrast, the structural disorder in glasses makes it challenging to directly identify defects at the particle ...

Topological defects are dislocations, or other structural oddities, that are protected from annihilation by mathematical symmetries. A well-known example is skyrmions, which are a twisted spin ...

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.
