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 ...

Inside most of the Earth, olivine is a hot mineral whose creepy behavior drives plate tectonics. In the upper mantle — the top of the planetary layer between the crust and core — olivine's unusual ...

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

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 ...

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 ...

If we are to prevent the impending environmental crisis, it is imperative that we find efficient and sustainable ways to avoid being wasteful. One area with much room for improvement is the recycling ...

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 = ...

Dr. Mitsutaka Haruta (presently, in NIMS) and Assoc. Prof. Horoki Kurata (Institute for Chemical Research) demonstrated the direct observation of molecular column in organic crystals using a scanning ...

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 ...
