【Abstract】 Recent progress in the development of atom probes, especially the three dimensional atom probe (3DAP) and their applications to interface studies of metallic materials is briefly reviewed. By employing a 3DAP it is possible to determine the position of a single atom and at the same time to identify its species. Thus 3DAP can map out elemental distribution in real space with almost atomic resolution. Unique features of the atom probe (AP) are demonstrated by describing recent applications of conventional atom probes and the 3DAP to interface chemical analysis of metallic materials.更多还原
