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 ...

Much of modern electronic and computing technology is based on one idea: add chemical impurities, or defects, to semiconductors to change their ability to conduct electricity. These altered materials ...

Some imperfections pay big dividends. A Cornell-led collaboration used X-ray nanoimaging to gain an unprecedented view into solid-state electrolytes, revealing previously undetected crystal defects ...

Most materials, especially metals and ceramics, are crystals. Their atoms are arranged in three-dimensional lattices that ...

Demonstrating that a material thought to be always chemically inert, hexagonal boron nitride (hBN), can be turned chemically active holds potential for a new class of catalysts with a wide range of ...

Scientists at Caltech have figured out how to precisely engineer tiny three-dimensional (3D) metallic pieces with nanoscale ...

The rapid advancement of 2D materials (2DMs), such as graphene, transition metal dichalcogenides (TMDs), and hexagonal boron nitride (hBN), has revolutionized the field of nanotechnology and ...

Future devices will continue to probe the frontier of the very small, and at scales where functionality depends on mere atoms ...

Researchers developed a method that gradually adds and removes atoms in simulations, enabling realistic modeling of crystal defects that affect material strength.

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 ...
