In a first step one divides the Bravais lattices into 7 crystal systems which are defined by the lengths $a$, $b$, $c$ and angles $alpha$, $beta$,
Physics 927 E.Y.Tsymbal 2 Non-Bravais lattices are often referred to as a lattice with a basis. The basis is a set of atoms which is located near each site of a
A lattice system is a class of lattices with the same set of lattice point groups, which are subgroups of the arithmetic crystal classes. The 14 Bravais lattices are
The fourteen Bravais lattices begin to consider important locations within the crystal structure, called lattice points. An atom, collection of atoms, or
