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 ...

A study using EBSD and TEM imaging found that “b” dislocations in olivine occur in roughly 17% of analyzed crystals. These defects, once considered minor, may significantly influence mantle ...

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 ...

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 ...

Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current.

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 = ...

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 ...

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 ...

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 ...
