Electron crystallography can be used for determination of atomic structures of micrometer-/ nanometer-sized crystals, which are million times smaller than those required by X-ray crystallography. Structure determination at atomic resolution can be done from both high-resolution electron microscopy images combined with crystallographic image processing and electron diffraction data, or by combining them with powder X-ray diffraction data. Atoms may be overlapped in all projections if the unit cell of the crystal is large. In such cases, atomic structures can be obtained by collecting several diffraction patterns and images from different directions and combining them to reconstruct a three-dimensional potential map. In this paper, some recent developments of electron crystallography and its applications in structure determination of inorganic crystals in the past decade are shown.
