Diamond defects confirm 80-year-old theory of crystal stress

For the first time, researchers in Japan have directly mapped several components of the stress field surrounding an atomic-scale flaw in the crystal structure of diamond. Led by Tokuyuki Teraji at Japan's National Institute for Materials Science, the team achieved its result using nitrogen-vacancy (NV) centers in diamond, whose spin states respond differently to stress depending on how they are oriented relative to…
