Tomographic reconstruction of multiple in-line electron holograms of realistic objects
چکیده انگلیسی
In theoretical low energy electron point source microscopy, simulated holograms are made and used to reconstruct atomic clusters. In previous investigations, simple test clusters were used for convenience. In this paper we explore more realistic structures composed of a single type of atom such as diamond, graphite and Buckminsterfullerene-all of which consist of carbon atoms. We also examine clusters with two or more distinct atom types, including TiO2, CuO, Pt3O4, Ga3Pt5, WC, MgCO3, and MgO. Reconstructions from a single hologram do not give atomic resolution, and consist instead of 'spurious peaks' that are not located at atomic sites, as well as 'atomic peaks' close to atomic sites. Here we apply methods we developed previously to remove all spurious peaks. We show final reconstructions that consist only of atomic peaks located very close to atomic sites.
