WebPrimitive translation vectors Zones bounded by planes defined by equation 38 are consistent with the reduced-vector zones. These reciprocal-lattice planes are simply the planes bisecting the vectors K and normal to them. It is noteworthy that lattices with the same type of translational symmetry have equivalent zone patterns since zone structure … WebOne way is to repeat the primitive unit cell at each translation vector, ... The primitive lattice vectors are not unique; different choices for the primitive lattice vectors are possible. Another common way to specify crystal is to give the lattice parameters $(a,b,c,\alpha,\beta,\gamma )$, the space group, and the asymmetric unit.

Webwhere ’is the angle between the two primitive translation vectors. Equation (3)/(4) is not only necessary, but also a su cient condition for three/two translation vectors to form a primitive set in 3D/2D. This is obvious from the necessary and su cient condition of having exactly one site of Bravais lattice per primitive parallelepiped ... WebThe primitive cell of the FCC lattice is defined by the translation vectors: a 1 = ‰ a (x + y) a 2 = ‰ a (y + z) a 3 = ‰ a (z + x) where x, y, and z are the Cartesian unit vectors. These translation vectors connect the lattice pt at the origin to the points at the face centres. The angles between the axes are 60°

WebFor a primitive lattice the volume of the unit cell, i.e. a 1 a 2 a 3 & & & is minimum. The corresponding translation vectors are referred to as primitive translation vectors. Note that the primitive unit cell is not unique. Conventional unit cells are defined by non-primitive axes. A primitive unit cell contains one lattice point per cell.
