Code speedup strengthens researchers' grasp of neutrons

Neutrons are notoriously slippery subatomic particles. On their own, they break down in a matter of minutes, but within the confines of the atom's nucleus, neutrons are a foundational piece of nearly all known types of matter ...

First ab initio method for characterizing hot carriers

One of the major road blocks to the design and development of new, more efficient solar cells may have been cleared. Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) have developed the first ab initio ...

Electron-hole recombination mechanism in halide perovskites

A research team led by Prof. Zhao Jin from Department of Physics, University of Science and Technology of China (USTC) of the Chinese Academy of Sciences found low-frequency lattice phonons in halide perovskites resulting ...

Theory reveals the nature of silicon carbide crystals defects

Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications. Using silicon carbide ...
