What is the real resolution that can be realized in practical electron microscope operation? We have investigatedthis problem for TEM imaging in a systematic study on Ce-doped yttrium orthoaluminate,YAlO3. Employing a FEI Titan G3 50-300 (PICO) electron microscope equipped with the new CEOS CCOR+corrector for spherical (CS) and chromatic aberration (CC) we studied the conditions to resolve the57 pm Y-Y-atom pair distance in projection along [010]. Our successful imaging of this pair proves arecord resolution for direct 200 kV TEM imaging [1].
