Concept explainers

Crystal Lattices and Unit Cell

Consider a crystal. The regular and repeating pattern of constituent particles is the most distinguishing feature of crystalline solids. A crystal lattice is formed when these particles are replaced with representative points. The three-dimensional arrangement of constituent particles is known as a crystal lattice. Unit cell is that the smallest portion of a space lattice which when repeated in several directions, generate the whole lattice. Unit cell is a building block of a lattice. It is the smallest unit of cell.

Question

2.) A newly designed superconductor material has 3 different types of atoms in its molecular
formula and has a crystal structural similar to diamond cubic with an additional atom at the
body-center (like BCC). Atom A orients on the 8 vertices of the cubic lattice and at the body
center. Atom B orients at the center of each face. Atom C orients at 4 tetrahedral sites residing
entirely within the cubic lattice. Each cubic crystal lattice has precisely the number of atoms
that matches the molecular stoichiometry: AxByCz. What is the stoichiometry of this
material?
