Seeing is believing,征与分析段已经成多数学科究中不可少的要组成部。使电子显微对微
组织进行观察是表征与分析的重要一环。固体中的微观组织结构,如空位、位错、表面与界面、裂纹等,其性质往往
决定了固体本身的性能。随着材料科学、纳米技术、薄膜技术及精密加工等学科方向的发展,微观组织与性能的关系
越来越受到关注,例如:通过控制点缺陷可以改变二维材料的性质,通过改变位错的分布和运动状态可以强化材料,
采用表面加工改性可以提升和改善薄膜能耐,以及改善粉末冶金和增材制造的产品性能,通过晶界工程学可以获得超

Seeing is believing, characterization and analysis are essential components for researches in many areas.
Investigation of microstructure by using electron microscopy is one of the most important and challenging part for
characterization. As the advances of materials science, nano-tech, thin films, and precision machining, lots of
attentions have been drawn to the observation and manipulation of microstructure. For instance, the manipulation of
point defects can modify the properties of two-dimensional materials, the mechanical properties of materials are
controlled by the distribution and evolution of dislocations, the modification of interfaces structure can change the
property of films and increase the product quality of additive manufactured materials, grain boundary engineering
has been used to strengthen metals, deposition of films can increase the resistance to fracture, corrosion and
irradiation. The ability for characterization and analysis of microstructure is critical for students planned to work in
area of design of structural materials, thin films, semiconductor, micro- and nano- devices, precision machining, and
additive manufacturing.
The objective of this course is to acquaint both undergraduate and graduate students in Mechanical Engineering,
Materials Science and Engineering, Applied Physics, Chemistry, Aerospace Engineering, and Microelectronics
Science and Engineering with fundamental theory, application and analysis methods of microstructure, and enhance
the student’s ability of understanding and using the theory of microstructure formation and evolution to solve
engineering problem. By acquainting student with the basic theory and characterization methods in scanning
electron microscopy, focused ion beam, transmission electron microscopy, and electron back-scattering diffraction
pattern analysis, improve their understanding of microstructure in different scales, and promote their researching and
working ability in the related field.
After the course, the undergraduate students should be able to:
1. Know Miller index and basics of Crystallography. Understand the basic thermodynamics used in analysis of
microstructure, and the connection between energy and atomic arrangement.
2. Know different kinds of defects in solid and their importance in science and engineering.
3. Know the fundamental methods for characterizing microstructure, atomic configuration, roughness, 3D
tomography, and composition distribution of surface and interface, and understand their basic principles.
4. Know the interaction between electrons and solids. Know the usage of different type of signals.
5. Describe the theory of imaging and investigation methods in scanning electron microscope, focused ion
beam and transmission electron microscope. Know the cons and pros of scanning electron microscope and
transmission electron microscope. Know the meaning of contrast, resolution, depth of field in microscope.
6. According to practice in class, know the general requirement, editing method and typical typeset.
