Fine crystal lattice fringes observed using a transmission electron microscope with 1 MeV coherent electron waves

Abstract

A transmission electron microscope with a 1 MeV cold field-emission electron source has been developed for coherent and penetrating electron waves. We confirmed the coherence and overall stability of the microscope by observing Au(337̄) lattice fringes. These fringes have a 0.498 Å spacing.
