Most materials, especially metals and ceramics, are crystals. Their atoms are arranged in three-dimensional lattices that repeat the same exact pattern, over and over again. But there's a well-known ...

The study of curvature effects on crystal structures and defect dynamics offers pivotal insights into how geometric constraints influence material properties at the micro‐ and nanoscale. Curved ...

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 = ...

Point defects (e.g. missing, extra or swapped atoms) in crystalline materials often determine the actual electronic and optical response of a given material. For example, controlled substitutions in ...

Researchers developed a method that gradually adds and removes atoms in simulations, enabling realistic modeling of crystal defects that affect material strength.

Defect-filled lead-halide perovskites rival silicon solar cells because domain walls inside the material separate and guide charges. Researchers visualized these charge-transport networks using a ...

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 ...

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 ...

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 ...
