Outline of Research at the Start

本研究では、シュリーレン電子顕微鏡法(2次元シュリーレン法)の開発を行う。ここで重要となる技術項目は以下の3点である。
① シュリーレン法
② ホロコーン照明、およびホロコーン・フーコー法
③ ラミノグラフィー
このうち①と③については電子顕微鏡で実施された例は無く、②についても本研究提案者らが、2019年春に発表した例があるのみである。
すなわち、電子顕微鏡以外の分野の技術・方法を電子顕微鏡に取り込むことによって、これまで観測できなかった新しい物性情報の計測法とそのためのシュリーレン電子顕微鏡の開発を実現することを目的とした研究である。

Outline of Final Research Achievements

Schlieren electron microscopy that can visualize and measure a spatial electromagnetic field distribution inside the materials and around the specimens was developed by Schlieren microscopy as phase observation methods and by laminography as three-dimensional measurement techniques. With this developed microscopy by using non-interference-type thermal transmission electron microscopes, we succeeded to observe electromagnetic fields with a wider view area than that by electron holography.
Furthermore, Lorentz SEM/SIM methods that can visualize electromagnetic field in sub-mm area by using conventional scanning electron/ion microscopes, and Lorentz microscopy and electron holography that can observe the high electromagnetic fields of 500 mT were also developed.
As a result of this research, many technical methods for observing and visualizing the spatial electromagnetic fields have been practically realized and can be used for various applications.

Academic Significance and Societal Importance of the Research Achievements

本研究では、汎用型の電子顕微鏡を用いて電子線ホログラフィーなど実用化されている干渉計測法では計測が困難な、広範囲の空間電磁場の可視化を可能とする技術開発を行った。sub-mmサイズからsub-μmサイズまでを広く、かつ廉価にカバーできる電子顕微鏡手法である。今後、バイオ系を含む様々な装置開発、材料のマクロスコピックからメゾスコピックな物性解析に応用されるだけでなく、光学の原理、結像理論に根差している手法であるため、解析法の習得を通して、これら分野の教育にも利用されると期待される。
