HIGH-RESOLUTION ELECTRON MICROSCOPE IMAGES OF CRYSTAL LATTICE PLANES USING CONICAL ILLUMINATION

Abstract

The (111)-, (200)-, and (220)-lattice planes of small vapor-deposited gold crystals with 2.35-, 2.04-, and 1.44-Å respective interplanar lattice spacings were resolved by high-resolution transmission electron microscopy. The simultaneous resolution in one micrograph of the three different lattice spacings and the elimination of azimuthal orientation preferences of the imaged lattice planes were achieved by using conical instead of axial specimen illumination methods.
