Doping semiconductors such as silicon with select impurity atoms is a common method for customizing the material’s electronic properties for various applications. Yet atomic-level control and understanding of doping processes remain elusive. Some of those details have now been revealed by a study that pinpointed the three-dimensional position and elemental identity of the atoms in doped silicon nanowires (Nature, DOI: 10.1038/nature11999). Such nanowires are already used . . .
