WebMay 14, 2024 · In the diagram on the right above, the blue atoms have been placed above the white (unoccupied) void spaces in layer A. Because this third layer is displaced horizontally (in our view) from layer A, we will call it layer C. the sequence of layers is A-B-C-A-B-C-A-B-C..., so we call it ABC packing. WebApr 14, 2024 · The AlTiN unit cells in this study are built with the latter. AlN, with the space group Fm-3m (group number 225), crystallizes in the face-centered cubic structure. The lattice constants are as following: a = b = c = 3.78 Å, α = β = γ = 90° [16].

WebAPF is basically the fraction of atoms to void. For a full article explaining APF, check out this link. The total volume of the unit cell is just the volume of a cube. The cube side length is a, the volume is . Now we need to count how many atoms are in each unit cell. WebThe primitive cells created by this method are called Wigner-Seitz unit cells. Rather than splitting the atom to put ⅛ of it on each of the 8 corners, the Wigner-Seitz unit cell has a single atom surrounded by empty space. Wigner-Seitz cells are unique, but they are not that intuitive to understand as a crystal structure.
