Lattice and crystalline structures (Oct. 25, 27 (4h), Nov. 6))
Schema della sezione
-
Introduction to lattice structures: Bravais lattices and crystalline structures in real space. Lattices with basis (generalities; examples about the conventional cells of the cubic lattices; other relevant examples: diamond, graphene, graphite). Packing fraction.
Other examples of Bravais lattices with basis: zincblende, rocksalt, wurzite (one slide). Wigner-Seitz cells. Reciprocal lattices. Families of lattice planes
Miller indices. Brillouin zone. X-ray diffraction: Bragg and von Laue. Structure factor.
