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 ...

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 ...

Researchers show that Cartan's First Structure Equation links crystal defects to the same mathematical rules governing electric currents and magnetic fields. (Nanowerk News) A fundamental goal of ...

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 ...

Half-Heusler Ni-based alloys are thermoelectric materials with the potential for converting waste heat into electricity. However, the origin of their impressive conversion efficiency is not entirely ...

Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications.

Researchers discovered that crystal dislocations in antiferroelectric PbZrO3 thin films generate ordered polar antihedgehog lattices, creating a new defect-engineering approach for polar topologies.

Applying a high magnetic field simulates microgravity conditions that suppress melt convection in germanium single crystal ...

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 = ...

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 ...

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 ...
