Crystal Viewer Lab Exercise
Teaching Materials | 28 Jun 2010 | Contributor(s):: Gerhard Klimeck, Parijat Sengupta, Dragica Vasileska
A central problem in the investigation of material properties involves the examination of the underlying blocks that aggregate to form macroscopic bodies. These underlying blocs own a definite arrangement that is repeated in three dimensions to give the crystal structure. We will try to explore...

Crystal Structures
Teaching Materials | 08 Jun 2010 | Contributor(s):: David K. Ferry, Dragica Vasileska, Gerhard Klimeck
In mineralogy and crystallography, a crystal structure is a unique arrangement of atoms in a crystal. A crystal structure is composed of a basis, a set of atoms arranged in a particular way, and a lattice. The basis is located upon the points of a lattice spanned by lattice vectors, which is an...

Crystal Directions and Miller Indices
Teaching Materials | 08 Jun 2010 | Contributor(s):: David K. Ferry, Dragica Vasileska, Gerhard Klimeck
Miller indices are a notation system in crystallography for planes and directions in crystal lattices. In particular, a family of lattice planes is determined by three integers, l, m, and n, the Miller indices. They are written (lmn) and denote planes orthogonal to a direction (l,m,n) in the...
