WebApr 9, 2024 · 1.Introduction. The problem of synthesis of continuous, crystalline perfect semiconductor solid solutions based on group IV of the periodic system of elements and chemical compounds A III B V, A II B VI seems to be an urgent task of modern microelectronics. In the field of solid solutions, depending on the chemical composition, it … In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions, or molecules in a crystalline material. Ordered structures occur from the intrinsic nature of the constituent particles to form symmetric patterns that repeat along the principal directions of three-dimensional space in … See more Crystal structure is described in terms of the geometry of arrangement of particles in the unit cells. The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. The geometry of the … See more Real crystals feature defects or irregularities in the ideal arrangements described above and it is these defects that critically … See more Polymorphism is the occurrence of multiple crystalline forms of a material.

As the entire crystal consists of repeating unit cells, this definition is sufficient to represent the entire crystal. Within the unit cell, the atomic arrangement is expressed using coordinates. There are two systems of coordinates commonly in use, which can cause some confusion.
