This graduate-level course covers the fundamentals of crystallography, chemical group theory, and their application in materials research. The topics include the geometric/algebraic representations of symmetry operations, point groups, Bravais lattice, space groups, reciprocal space, x-ray/electron/neutron diffraction techniques, Rietveld refinement, pair distribution function, real-space crystallography methods, etc.. Particularly, the course will also briefly introduce the cutting-edge aberration-corrected scanning transmission electron microscopy technique, a rapidly developing real-space crystallography method that allows for direct atom-by-atom observation. All lectures of this course will be delivered in English.

This undergraduate-level course introduces elementary crystallography, especially the symmetry in solids. The content focuses on symmetry operators, crystal system, point groups, direct lattice and reciprocal lattice, space groups, some representative crystalline structures, etc.. Basic x-ray diffractions, surface and interface structure are also included.
