Across the physical world, many intricate structures form via symmetry breaking. When a system with inherent symmetry ...
Wafer breakage is the most serious impact of killer crystalline defects. About 0.1 to 0.2% of silicon wafers break. The higher the number of wafer breakages, the slower the time to market. Given the ...
Topological defects govern how many advanced materials behave, but predicting them has traditionally required slow, ...

Alloy design model offers faster, more accurate predictions by factoring in material defects
The new model takes into account an important class of material defects (grain boundaries) and the tendency of the mixed solutes to gather—or segregate—around the structural imperfections during alloy ...
New GPU-accelerated modeling reveals the hidden mechanics behind graphene’s AB-BA transitions and the defects that freeze them in place. Study: Phase-Field Crystal Method for Bilayer Graphene. Image ...
α-FAPbI 3, a promising solar cell material with a cubic perovskite structure that is metastable at room temperature, can be stabilized by introducing a pseudo-halide ion like thiocyanate (SCN –) into ...
Researchers have looked at what limits the efficiency of a promising solar material to reveal the nature of multiple different kinds of defects, their varied roles in device efficiency and their ...
Researchers and industries have been using transmission electron microscopy (TEM) to study semiconductors' stacking and dislocation faults. This article considers the analysis of crystal structures.
(Nanowerk News) Two-dimensional materials are essential for developing new ultra-compact electronic devices, but producing defect-free 2D materials is a challenge. However, discovery of new types of ...
