A New approach for three-dimensional atomic-image reconstruction from a single-energy photoelectron hologram

Matsushita, Tomohiro*; Agui, Akane; Yoshigoe, Akitaka 

A "scattering pattern matrix" method is proposed here to overcome the difculties presented by photoelectron holography, such as forward-scattering and multi-energyproblems. This method makes it possible to reconstruct a three-dimensional atomic arrangement from a single-energy hologram. We have utilized the "scattering pattern matrix" that includes the angular variation of the scattered object waves, and we have adopted a specialaverage process and the gradient projection method for minimizing the mean-squared error. The reconstruction of the Si bulk structure is demonstrated by using an experimental Si(111) 2s single-energy hologram.
