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 ...

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 ...

Crystals are known far and wide for their beauty and elegance. But even though they may appear perfect on the outside, their microstructure can be quite complicated, making them difficult to model ...

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 ...

A new hybrid layered perovskite featuring elusive spontaneous defect ordering has been found, report scientists. By introducing specific concentrations of thiocyanate ions into FAPbI3 (FA = ...

Ultrafast optical measurements expose buried crystal flaws in atom-thin insulating films, offering a non-destructive route to ...

Using hard X-ray photoemission spectroscopy, researchers revealed how oxygen vacancies and structural disorder influence subgap state formation. The figure shows the InGaZnO 4 crystal structure, the ...

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.

Forward-looking: Researchers at the University of Chicago have achieved a groundbreaking milestone, storing terabytes of digital data within a crystal cube just one millimeter in size. They ...

Defect bits: representation of two n-bits along a defect line (shown in black). Shown are the orientations of the rod-like molecules that comprise liquid crystals. (Courtesy: Žiga Kos and Jörn ...

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 ...
