We are studying defects, sub-nanoscale precipitates and interface segregations of impurity/solute atoms in materials. Our target extends from nuclear materials such as reactor pressure vessel steels and shroud stainless steels to semiconductors such as silicon and germanium. We employ positron annihilation, atom probe tomography, electron microscope, etc. By combining various theoretical calculations with the above experiments, we are clarifying the formation and microscopic structures of these defects, precipitates and interface segregations.
