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 ...
Recently, organic–inorganic halide perovskite (OIHP) solar cells have become one of the most appealing research topics. Due to their ionic nature, intrinsic defects, such as vacancies and ...
(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 ...
A recent article in Scientific Reports detailed the characterization of disordered structures in graphene and monolayer hexagonal boron nitride (hBN) induced by low-energy argon ion irradiation. The ...
Positron Annihilation Spectroscopy (PAS) is a highly sensitive, non-destructive method for probing atomic-scale imperfections in a broad spectrum of materials, from metals and ceramics to polymers and ...
