  • Page ID
  • This TLP has covered the following topics:

    • The mathematical description of the atomic structure of a crystal.
    • The different lattice types.
    • What a lattice vector, unit cell & motif are and how they are relevant to describing crystals.
    • Close packing and the packing efficiency of a crystal structure.
    • What symmetry operators are present within a crystallographic lattice and how only specific combinations of such symmetry elements may exist.
    • Bravais lattice and Point Groups.
    • How to construct the plan view of a 2×2 unit cell.
