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.
Their often unique and exotic properties, which stem from perovskite’s peculiar crystal structure ... the precise ordering of a perovskite’s defects, such as vacancies or substitutions.
Now a new Northwestern study finds how defects affect two-dimensional crystalline structures, and the results hold information for designing new materials. In packed, two-dimensional crystalline ...
(Nanowerk News) A study published by researchers at the CEA challenges the ways in which defects in crystal structures are described, proposing a novel approach to characterizing and modeling crystal ...
Northwestern University researchers track 3D printed metal defects in real-time, paving the way for stronger, more reliable ...
The fact that the crystal structure differs from the structure immediately around the linear defect should therefore also affect how the metal deforms. In the worst case, it tears rather than deforms.
Defects, or imperfections ... have the same composition of elements as the host crystal, the changes in electronic band structure at the dislocation core, due to symmetry-reduction and strain ...
All-perovskite tandem solar cells (TSCs) are a class of solar cells comprised of two or more sub-cells that absorb light with ...
"Ultimately, we hope to observe how these defects can be used to control how calcite reacts," Fenter added. The ability to ...
"But CVD graphene is 'stitched' together from many small crystalline grains -- like a quilt -- at grain boundaries that contain defects in the atomic structure," Kysar explains. "These grain ...
They look at irregular sites - called ‘defect centers’ - in the crystal structure of the mineral quartz, which frequently appears in sedi-ments. Their study has been published in Geophysical ...
