A geometric arrangement of the points in space at which the atoms, molecules, or ions of a crystal occur. Also calledspace lattice. ...
Crystals are defined in terms of space, population, and mutual arrangement. Crystal space is represented as an indefinitely extended lattice of periodically repeating points. The periodicity of the lattice is defined by the lengths and mutual orientations of three lattice vectors that enclose the patt...
In this structure, which is also known as the alkali halide or rocksalt structure (碱金属卤化物或者称为岩盐结构), each point of the FCC lattice is assigned a basis of one unit of NaCl: Na (groupIatom) at(0,0,0)and Cl (groupVIIatom) ata(1/2,1/2,1/2)(or vice versa), as show...
A basic concept in crystal structures is the unit cell. It is the smallest unit of volume that permits identical cells to be stacked together to fill all space. By repeating the pattern of the unit cell over and over in all directions, the entire crystal lattice can be constructed. Acube...
These points are known as lattice point or lattice site. Lattice points in a crystal lattice are joined together by straight lines. By joining the lattice points with straight lines the geometry of the crystal lattice is formed. Unit Cell:The smallest portion of a crystal lattice is called Uni...
A crystal lattice. As we can observe from Fig. 2.1, a crystal lattice can be broken down into a fundamental unit called the unit cell. The crystal lattice is made of a repetition of this unit cell. A unit cell is not unique; a crystal lattice can be constructed from a repetition of ...

The other six systems, in order of decreasing symmetry, are hexagonal, tetragonal, trigonal (also known as rhombohedral), orthorhombic, monoclinic and triclinic.Bravais lattice is a set of points constructed by translating a single point in discrete steps by a set of basis vectors. In 1848, ...
where\(\bar n\)is the average refractive index of LCs1,120. Thus, CLCs are also known as soft photonic crystals, i.e., periodic dielectric materials with photonic band gaps (PBGs). Sustaining efforts have been devoted to dynamically and multi-dimensionally controlling the CLC helical configurat...
The magnitude of lattice distortion also plays a pivotal role in controlling materials’ properties, as exemplified by the spin-valley locked state16 observed in BaMnX2 (X = Sb and Bi)17,18,19. Both compounds consist of the X4 layers forming X–X zig-zag chains due to the X-atom displac...
