WebTo effectively make use of Deep Learning methods to model these materials, we need to utilize the symmetries present in the crystals, which are defined by their space group. Existing methods for crystal property prediction either have symmetry constraints that are too restrictive or only incorporate symmetries between unit cells. WebUnit cell. In the case of a rectangular two dimensional lattice the unit cell is the rectangle, whose sides are the vectors a1 and a2. If the unit cell is translated by all the lattice vectors expressed by Eq.(1), the area of the whole lattice is covered once and only once.
