Materials that emit and manipulate light are at the heart of technologies ranging from solar energy to advanced imaging systems. But even in well-studied materials, some fundamental behaviors remain ...

As TOPCon cell efficiencies push past 25% and process windows narrow, the cheapest defect to fix is the one caught earliest.

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 ...

Perovskites are among the most extensively studied materials in modern materials science. Their often unique and exotic properties, which stem from perovskite’s peculiar crystal structure, could find ...

An electron-beam technique that can precisely create thousands of atomic defects in a crystal could be used to build quantum devices. Read the paper: Mesoscale atomic engineering in a crystal lattice ...

Half-Heusler Ni-based alloys are thermoelectric materials with the potential for converting waste heat into electricity. However, the origin of their impressive conversion efficiency is not entirely ...

Insights into atomic-scale defects may enable next-generation thin-film transistors for smartphones, televisions, and flexible electronics. (Nanowerk News) Many displays found in smartphones and ...
