Crystal

A material in which the atoms are arranged in a definite geometric pattern. These arrangements have a direct effect on the physical properties of the material. These arrangements commonly take the form of cubes, rectangular solids, hexagonal solids.....etc. Most crystals contain defects that can strongly affect their optical and electrical properties.

Orientation

Arrangements in space of the axes of a crystal lattice with respect to a coordinate system.
