WebFCC has 4 atoms per unit cell, lattice constant a = 2R√2, Coordination Number CN = 12, and Atomic Packing Factor APF = 74%. FCC is a close-packed structure with ABC-ABC stacking. Don’t worry, I’ll explain what those numbers mean … WebEach atoms is shared by three neighbors in the the same layer and with another hexagonal prism on top or below. So they count as 2 × 6 × 1 3 × 1 2 = 2 atoms. The total count thus is 6. These diagrams of the hexagonal closest packing, do not represent the the unit cell as the most simple unit from which the crystal is build by symmetry ...
WebUsually, primitive cells in two and three dimensions are chosen to take the shape parallelograms and parallelepipeds, with an atom at each corner of the cell. This choice of primitive cell is not unique, but volume of primitive cells will always be given by the expression above.
