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 ...

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 ...

Furthermore, investigating how defects migrate and interact over time, particularly under different external stimuli such as temperature changes or mechanical stress, could provide deeper insights ...

We investigate the band structure of metal-dielectric photonic crystals comprising stacked organic semiconductor microcavities with silver metal mirrors incorporating crystal defects: individual unit ...

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.

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 ...

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 ...

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

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 ...

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.

Ripples and imperfections in liquid crystals like those found in TVs could be used to build a new type of computer. Žiga Kos at the University of Ljubljana in Slovenia and Jörn Dunkel at the ...

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 = ...
