High-Resolution Holography Observation of H-Nb₂O₅

Abstract

Electron holograms of H-Nb 2 O 5 are formed from about 150 diffracted waves used to reconstruct high-resolution images. A niobium atom arrangement in H-Nb 2 O 5 is observed in an aberration-corrected phase image. A hologram with 9.3-pm carrier fringes is also formed. It is the finest carrier fringe spacing hologram ever reported.
