The One-Angstrom Microscope will resolve images to a single angstrom using an electron beam energy of only 300 kV.
Current and future capability for high resolution transmission electron microscope: At left, actual ARM micrograph of an interface in the ceramic oxide rutile imaged at the current resolution limit of 1.6 angstroms. At right, computer image simulation of same interface at 1 angstrom resolution, clearing showing the position of oxygen atoms (red) not visible in ARM micrograph. The sketch of overlapping contrast transfer functions illustrates the basic method of operation of the One-Angstrom Microscope.
