WebNov 26, 2024 · In crystallography there are conventions as to how the indices of planes and directions are written. When referring to a specific plane, "round" brackets are used: (2.4.1) ( h k l) When referring to a set of planes related … Crystallographic directions are lines linking nodes (atoms, ions or molecules) of a crystal. Similarly, crystallographic planes are planes linking nodes. Some directions and planes have a higher density of nodes; these dense planes have an influence on the behavior of the crystal: • optical properties: in condensed matter, light "jumps" from one atom to the oth…
