Crystal c axis
Did you know?
WebThe "c" axis is usually taken as being longer than the "a" axes. The hexagonal crystal structure is an anisotropic structure. If one looks at the 4 axes it is easy to see that the appearance of these axes will not change if the whole structure is rotated 120° positive or negative about the "c" axis. WebSapphire is a uniaxial crystal, and its optical axis is the c-axis 〈 0001 〉. Therefore, it has birefringence, and birefringence appears when light is incident from a direction at an angle to the optical axis. When light is incident parallel to the c-axis, the optical axis, the refractive index is limited to only one kind, but when polarized ...

Performing certain symmetry operations on the crystal lattice leaves it unchanged. All crystals have translational symmetry in three directions, but some have other symmetry elements as well. For example, rotating the crystal 180° about a certain axis may result in an atomic configuration that is identical to the original configuration; the crystal has twofold rotational symmetry about this axis.
