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 ...

Point defects (e.g. missing, extra or swapped atoms) in crystalline materials often determine the actual electronic and optical response of a given material. For example, controlled substitutions in ...

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 ...

Philosophical Transactions: Mathematical, Physical and Engineering Sciences, Vol. 371, No. 1988, New frontiers in anisotropic fluid—particle composites (13 April 2013), pp. 1-15 (15 pages) Thin liquid ...

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

Understanding how atoms 'glide' and 'climb' on the surface of 2-D crystals like tungsten disulphide may pave the way for researchers to develop materials with unusual or unique characteristics, ...

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.

In an interview with pv magazine, Empa scientist Mirjana Dimitrievska explains that the CIGS photovoltaic technology, while promising for efficiency and flexible applications, faces persistent ...

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 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 ...
