Zone axis, a term sometimes used to refer to "high-symmetry" orientations in a crystal, most generally refers to any direction referenced to the direct lattice (as distinct from the reciprocal lattice) of a crystal in three dimensions. It is therefore indexed with direct lattice indices, instead of with Miller indices. High-symmetry zone axes through a crystal lattice, in particular, often lie in the direction of tunne… WebThat’s why we only need to describe 3 different vectors, as long as they come from 3 different edge sets).The cube is the highest-symmetry lattice shape. All 12 edges are the same length and they all have the same angle to each other (90°), which can be represented as 3 vectors of identical length, at 90° to each other. Web14 hours ago · For Cvac, there are two structures after structure optimization, as shown in Fig 1.The total energies and symmetry of these structures are listed in Table 1.The structure in Fig. 1 (a)(b) (recorded as Cvac-I) is obtained by structure optimization with symmetry.
