On the periodicity of the crystal. We know that it is associated with the lattice constant, or in other words, the distances between the nuclei of the atoms of the element. But another frequency for the conduction electrons follows from this work, it creates the valence electrons or electrons of the atomic core, which is probably localized and are on the boundary of the conduction band.

 Now, when microelectronics turned into nanoelectronics and threatens to go to angstromelektronics, it is important to know the patterns of distribution of atoms (atomic size is measured in units of Angstroms) in the crystal lattice of the single crystal.
