Abstract

Images of near-surface atoms can be obtained from photoelectron diffraction data by various imaging algorithms, the basic method being: (a) a Fourier transform over k-space involving a path-length difference phase factor. We will also discuss two recently proposed direct methods that compensate for the non-optical atomic scattering of photoelectrons: (b) a Fourier transform of small k-space cones centered on the approximately optical scattering regions of a photoelectron diffraction data set; and (c), a truly quantum mechanical Fourier transform that accounts for the non-optical propagation and atomic scattering of the photoelectrons in the first Born approximation. Atomic images produced by these three methods are compared for photoelectron diffraction patterns calculated from a single scattering Ni trimer, and a large multiple scattering Ni bulk cluster. All three methods are found to comparably resolve backscattering atomic images, while poorly resolving forward and side scattering atomic images.
