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 ...

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 ...

An international team of researchers, led by University of Toronto Engineering Professor Yu Zou, is using electric fields to control the motion of material defects. This work has important ...

Ion implantation introduces energetic ions into a crystal lattice, displacing atoms and creating point defects—vacancies and interstitials—collectively known as Frenkel defects. These primary defects ...

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.
