The seven crystal systems are triclinic, monoclinic, orthorhombic, tetragonal, trigonal, hexagonal, and cubic. Informally, two crystals are in the same crystal system if they have similar symmetries (albeit there are many exceptions).

The orthorhombic space groups are best divided into three groups based on crystal class: those that contain just 2 or 2 1 axes (class 222), those that contain a single 2 or 2 1 axes plus two mutually perpendicular planes (class mm 2), and those that are centrosymmetric with both 2 or 2 1 axes and three mutually perpendicular planes (class mmm ).

In this study, εGa 2 O 3 thin films were grown by mist chemical vapor deposition on a hexagonal (0001) GaN template and a cubic (111) SrTiO 3 (STO) substrate. By analyzing the obtained Xray diffraction (XRD) φscans, it was found that the εGa 2 O 3 epitaxial thin films grown on both GaN and STO exhibited an orthorhombic structure. In addition, a method was proposed to distinguish between ...

The Orthorhombic Crystal System. In the orthorhombic system, the conventional unit cell is a parallelepiped defined by three mutually orthogonal vectors of unequal length: A1 A2 A3 = = = ax^ by^ cz^, so that a = b = c, but α = β = γ = π/2. It is a limiting case of the conventional monoclinic crystal with β → π/2.
