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 ...

One well-known example of such material defect that has been studied extensively over the past century, Upmanyu says, is a dislocation. It occurs when an entire atomic plane is missing from a ...

Quantum magnetometers are able to detect and visualize the tiniest damage in ferromagnetic materials. In aerospace technology or the automotive industry, they can help to significantly increase the ...

Defects in transistors, such as unwanted impurities and broken chemical bonds in the various layers of the semiconductor, can limit their performance and reliability. These defects are becoming harder ...

Researchers have discovered that engineering one-dimensional line defects into certain materials can increase their electrical performance. Materials engineers don't like to see line defects in ...
