| This single layer is the precursor of the body centered cubic (BCC) unit cell. The lattice
points are in the same general form as the simple cubic (SC) unit cell, with the exception
that the atoms are not touching one another. Reset Lattice |
| In order to generate the BCC unit cell, we need to place a second layer in the indentations of
the first layer, as shown in this figure. This can be seen if you rotate it until it is on its
side. The second layer is presented in blue in order to differentiate it from the first layer. Reset Lattice |
| To complete the BCC unit cell, the third layer is placed in such a way that it eclipses the first
one (pattern is therefore ABA). Can you see the BCC unit cell from the lattice? Rotate it until
you see it clearly. Reset Lattice |
