This lecture covers the fundamentals of electron diffraction, including the importance of electron diffraction in TEM images, Bragg's law, reciprocal lattice, Ewald sphere, multiple beam scattering, and deviation from Bragg condition. It also explores the applications of electron diffraction in understanding crystal structures and symmetry. The instructor explains the concept of lattice points, unit cells, crystal systems, and centering types in crystallography. The lecture delves into lattice vectors, lattice planes, and interplanar spacings in cubic crystals. Additionally, it discusses the effect of sample shape on diffraction patterns and the techniques for setting dark-field imaging conditions.
