A01 - Professor Hatsujiro Hashimoto Memorial Symposium: Foundations in Imaging Crystals, Defects, and Atoms

Satoshi Ichikawa, Osaka University, Japan
Masashi Watanabe, Lehigh University

Professor Hatsujiro Hashimoto is one of the pioneers in imaging crystalline solids by transmission electron microscopy (TEM). His many achievements include the development of TEM instruments and holders, pioneering work in atomic-scale imaging and early contributions in understanding diffraction contrast based on dynamical diffraction theory. In addition, Professor Hashimoto performed in situ observations at elevated temperatures as high as 3000°C in the 1960s, fabricated an environmental TEM instrument with a gas reaction chamber and challenged the field to image single atoms using spectrometry techniques in TEM. His tremendous scientific contributions influenced scientists not only in Japan but also across the world. This symposium is dedicated to the memory of Professor Hashimoto and will feature technical aspects spanning a broad range of topics representative of the significant breadth and scope of his work and achievements.

A02 - Atomic-scale Functional Imaging in Aberration-corrected Electron Microscopy

Miaofang Chi, Oak Ridge National Laboratory
Jing Tao, Brookhaven National Laboratory
Marta Rossell, Electron Microscopy Center, Switzerland

S/TEM capabilities of probing structure and chemistry at atomic resolution are routine in microscopy labs owing to the successful invention and implementation of aberration correctors two decades ago. Accompanying the high spatial resolution is the developments of new and revisited imaging and spectroscopy techniques stimulated by the use of aberration correctors along with the emerging new detectors and data analytics. Notably, the recent advancements in differential phase contrast imaging, precise measurements of atomic positions, atomic-scale holography, high resolution tilt-series tomography, depth sectioning with high convergence angles, and 4D data acquisition provides new imaging capabilities for not only structure and chemistry, but also functionalities of materials, bringing about a transformation in the way the materials being understood and designed. This symposium intends to foster discussions on recent and future developments and applications of aberration-corrected S/TEM.

First introduced commercially in 1965, the scanning electron microscope (SEM) has evolved into a core microscopy characterization tool for thick (electron-opaque) specimens, capable of imaging nanometer-scale features with a variety of contrast mechanisms: topographic, compositional, crystallographic, magnetic, and electrical potential. Augmented with energy dispersive X-ray spectrometry (EDS) and electron backscatter diffraction (EBSD), SEM can characterize morphology, elemental composition and crystal structure. Recently, amazing capabilities using STEM-in-SEM have been demonstrated making the SEM more valuable than ever for materials characterization. This symposium will present a comprehensive overview of SEM as a problem-solving tool whose capabilities are still being developed and extended.
