A Hall plane is a concept used in crystallography and solid-state physics to describe specific orientations within a crystal lattice. The term is often associated with "Hall groups" or the "Hall notation," which classify different types of plane symmetries and orientations in crystals. In crystallography, planes within a crystal are defined by Miller indices, which are a set of three integers that describe the orientation of the plane in relation to the axes of the crystal lattice.
