It is reported that lattice imaging with a 300 kV field emission microscope in combination with numerical reconstruction procedures can be used to reach an interpretable resolution of about 80 pm for the first time. A retrieval of the electron exit wave from focal series allows for the resolution of single atomic columns of the light elements carbon, nitrogen, and oxygen at a projected nearest neighbor spacing down to 85 pm. Lens aberrations are corrected on-line during the experiment and by hardware such that resulting image distortions are below 80 pm. Consequently, the imaging can be aberration-free to this extent. The resolution enhancement results from increased electrical and mechanical stability's of the instrument coupled with a low spherical aberration coefficient of 0.595 + 0.005 mm.

“…In 2000, Dr Tonomura and his collaborators developed an electron microscope with a 1-MV electron beam [5,44] having a penetration power more than twice that of the previous ones [32]. They used it to study the inside of high-T c superconductor thin films with a thickness of physical interest and to identify the features of vortex peculiarities of layered high-T c superconductors.…”

Lorentz microscopy has opened the door to observing a single quantized magnetic flux line (i.e. a vortex) and its dynamic behavior inside a superconductor in real time. It resulted from the efforts of Dr Akira Tonomura and his collaborators, who developed a field emission electron microscope and advanced the technologies used for visualizing vortices (e.g. a low-temperature specimen stage and a magnetic-field application system). They used a 1-MV field emission transmission electron microscope with an electron beam that can penetrate thick specimens of high-temperature superconductors (Bi 2 Sr 2 CaCu 2 O 8+δ and YB 2 C 3 O 7−δ ) to reveal the flux-line features inside materials and their interactions with defects. This memorial paper reviews the results of research in the area of vortex matter physics.Keywords quantized magnetic flux line, vortex, high-T c superconductor, electron holography, Lorentz microscopy, 1-MV field emission electron microscope

“…To peer deeper into the behavior of superconductors, Tonomura continued to develop the electron holography microscope, and, in 2000, he succeeded in the creation of a 1-million-volt (MeV) microscope (11). This microscope has the brightest beam and resolution of any transmission electron microscope, with a beam brightness of 2 ϫ 10 10…”
