Dissemination of IT for the Promotion of Materials Science (DoITPoMS)



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.
