Illustration of an intense laser pulse hitting a diamond crystal from top right, driving elastic and plastic waves (curved lines) through the material. The laser pulse creates linear defects, known as ...

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.

(Nanowerk News) An international team of researchers, led by Professor Yu Zou (MSE), is using electric fields to control the motion of material defects. This work has important implications for ...

AMES, Iowa – Materials engineers don’t like to see line defects in functional materials. The structural flaws along a one-dimensional line of atoms generally degrades performance of electrical ...

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 = ...

Using hard X-ray photoemission spectroscopy, researchers revealed how oxygen vacancies and structural disorder influence subgap state formation. The figure shows the InGaZnO 4 crystal structure, the ...

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 ...

Often admired for their flawless appearance to the naked eye, crystals can have defects at the nanometer scale, and these imperfections may affect the thermal and heat transport properties 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 ...
