Introduction to electron microscopy 3D reconstruction and its application in materials science

Electron microscopy 3D reconstruction is a well-established technique based on transmission electron microscopy to recover the three-dimensional structure of an object from a series of projection images at different viewing angles. A brief introduction to electron microscopy 3D reconstruction was illuminated in this paper. As an example,some practical experiences in electron microscopy3 D reconstruction with transmission electron microscope( Tecnai G2F20) for nano materials and semiconductor materials were introduced.
