Abstract
Photoelectron holography has been expected to be a powerful tool for visualizing three-dimensional (3D) local atomic structures around a photoelectron emitter atom. Photoelectron emitter atom sites with different elements can be distinguished by photoelectron kinetic energy. The elements of atoms reconstructed in atomic images, however, could not be assigned. We developed a method for the elemental characterization of the reconstructed atoms using a small difference of the scattered electron waves and demonstrated it using a measured InP(001) photoelectron hologram. Element assignment for both the emitter atom and the reconstructed atoms in 3D atomic images became possible.
