For my diploma thesis I got in Scherzer and Harald Rose were carrying touch with the group of Harald Rose that out a long time project on the correction worked in the field of theoretical particle of the spherical (Cs) and chromatic (Cc) optics. I was attracted by the ongoing aberration of a conventional Transmission aberration correction project due to Electron Microscope (TEM) by means of a familiar aberrations in electron optics I quadrupole-octopole correction system. At primary school in 1960, age 10 knew from my time as an optician. The The development of such a corrector was In 1950, I was born in a small historic town in Austria, where my parents Maximilian Haider and Anna Haider owned a watchmaker shop. My father had taken over his father´s shop, and my eldest brother stepped into their footsteps and became a watchmaker, too. To expand the business, it was agreed early in my childhood that I should become an optician. Therefore, I started working as an optician´s apprentice in Linz, Austria, when I was 14 years old. After the first optician certification exam I realized that the prospect of working as an optician for my whole life did not satisfy me.

Los tres investigadores se enfrentaron a un problema que obstaculizaba el desarrollo de la nanotecnología y que era considerado en gran medida irresoluble: la baja resolución de la microscopía electrónica. De hecho, mientras agencias estatales decidían dejar de financiar esta línea de investigación, los ganadores formaron un equipo con el objetivo de encontrar una solución. En menos de una década no solo tenían una respuesta teórica, sino también un prototipo de microscopio. Su técnica es la única que permite explorar la materia en la escala del picómetro, el equivalente a una centésima del diámetro de un átomo de hidrógeno –la billonésima parte de un metro–.

  • Advances and Applications of Atomic-Resolution Scanning Transmission Electron Microscopy
    Microscopy and Microanalysis (2021), 27, 943–995 doi:10.1017/S1431927621012125 Review Article Advances and Applications of Atomic-Resolution Scanning Transmission Electron Microscopy Jingyue (Jimmy) Liu Department of Physics, Arizona State University, Tempe, AZ 85287, USA Abstract Although scanning transmission electron microscopy (STEM) images of individual heavy atoms were reported 50 years ago, the applications of atomic-resolution STEM imaging became wide spread only after the practical realization of aberration correctors on field-emission STEM/ TEM instruments to form sub-Ångstrom electron probes. The innovative designs and advances of electron optical systems, the fundamental understanding of electron–specimen interaction processes, and the advances in detector technology all played a major role in achieving the goal of atomic-resolution STEM imaging of practical materials. It is clear that tremendous advances in computer technology and electronics, image acquisition and processing algorithms, image simulations, and precision machining synergistically made atomic-resolution STEM imaging routinely accessible. It is anticipated that further hardware/software development is needed to achieve three-dimensional atomic- resolution STEM imaging with single-atom chemical sensitivity, even for electron-beam-sensitive materials. Artificial intelligence, machine learning, and big-data science are expected to significantly enhance the impact of STEM and associated techniques on many research fields such as materials science and engineering,
