Local Structure Measurement Around Light Elements by Using Inverse Photoelectron Holography

The inverse mode of photoelectron holography (PEH) has a variety of major benefits compared with other atomic‐resolution holography techniques. One of the most significant is the ability to record holograms from emissions of light elements. We measured the O Kα holograms of Nb‐doped SrTiO3 using 1.5...

Zusammenfassung:The inverse mode of photoelectron holography (PEH) has a variety of major benefits compared with other atomic‐resolution holography techniques. One of the most significant is the ability to record holograms from emissions of light elements. We measured the O Kα holograms of Nb‐doped SrTiO3 using 1.5 and 20.0 keV incident electron beams and observed the differences in the holograms and atomic images between two different energies. This research presents basic measurements by a new technique of atomic‐resolution holography: Inverse Photoelectron Holography. This technique can measure three‐dimensional local structure around specific elements with laboratorial instrument. The authors measured the O Kα hologram of SrTiO3 with two different energies and obtained the local structure around oxygen. Two different patterns which include surface and bulky information are also obtained.
