First application of C{sub c} corrected imaging for high-resolution and energy-filtered TEM.
Contrast-transfer calculations indicate that C{sub c} correction should be highly beneficial for high-resolution and energy-filtered transmission electron microscopy. A prototype of an electron optical system capable of correcting spherical and chromatic aberration has been used to verify these calculations. A strong improvement in resolution at an acceleration voltage of 80 kV has been measured. Our first C{sub c}-corrected energy-filtered experiments examining a (LaAlO{sub 3}){sub 0.3}(Sr{sub 2}AlTaO{sub 6}){sub 0.7}/LaCoO{sub 3} interface demonstrated a significant gain for the spatial resolution in elemental maps of La.
