講義の概要とねらい

This course provides a comprehensive introduction to a range of microscopy techniques (viz. Optical and electron microscopies). The syllabus includes brief introduction to the structure of crystalline solids, imperfections in solid materials and basic concepts of microscopy. Students will explore the main construction and basic principles of various microscopy techniques, the strengths and weaknesses of each technique, and be better planned of selecting a suitable microscopy technique for their research purpose. Other topics include basics of optical properties, electron-solid interactions, electron diffraction and image formation, and discussion of different techniques of specimen preparations. Electron diffraction analyses and X-ray energy-dispersive spectrometry for microstructure characterization, phase identification and crystallography analyses of a wide spectrum of solid materials. A brief introduction to the very recent development of advanced aberration corrected scanning transmission electron microscopy for imaging and spectrometry at atomic resolution.

到達目標

By the end of this course, students will be able to:
(a) Understand the basic construction, capabilities and limitations of each microscopic technique.
(b) Understand the different modes of image formation in each microscopic technique for microstructure and crystallographic characterization in solid materials.

キーワード
