A crystal is a solid with a periodic atomic structure and a deviation from the periodicity of the crystal lattice is called a defect. Crystalline defects include point defects (e.g. colour centres) ...

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 ...

Scientists in the U.S. used sophisticated imaging techniques to observe previously unknown defects in the crystalline structure of a solid-state electrolyte. The scientists theorize that these defects ...

A fundamental goal of physics is to explain the broadest range of phenomena with the fewest underlying principles. Remarkably ...

PROVIDENCE, R.I. [Brown University] -- In 1972, physicists J. Michael Kosterlitz and David Thouless published a groundbreaking theory of how phase changes could occur in two-dimensional materials.

An international team of researchers, led by University of Toronto Engineering Professor Yu Zou, is using electric fields to control the motion of material defects. This work has important ...

For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without breaking. Their secret lies in tiny, line-like defects called dislocations, ...

Physicists in the US have gained new insights into one most of the basic phenomena in physics -- the melting of a solid. Arjun Yodh and colleagues at the University of Pennsylvania and Swarthmore ...

Researchers found a way to tune the spin density in diamond by applying an external laser or microwave beam. The finding could open new possibilities for advanced quantum devices. Electronic devices ...

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 ...
