This Demonstration gives insight into the crystal symmetries of five standard crystal symmetries of pure elements. These lattice symmetries are
1) simple cubic SC (e.g., polonium);
2) face-centered cubic FCC (e.g., copper);
3) body-centered cubic BCC (e.g., iron);
4) hexagonal closed-packed HCP (e.g., helium);
5) diamond DIA (e.g., silicon).
The direction
(h,k,l)
defines a plane to which this direction is perpendicular. This plane is called the crystal plane
(h,k,l)
. The three values
h
,
k
, and
l
are often referred to as Miller indices.
