Vibrations of the crystalline lattice are explained on the examples of monoatomic and diatomic lattice.
This set of slides describes the reciprocal space.
ABACUS: Test for Crystal Viewer Tool
05 Aug 2010 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
The objective of this test is to give an idea to a self-learning students or to instructors in the case this test is used in a classroom the level of understanding of this topic when students have gone through the learning material, worked exercises and have completed the assignments and the...

20 Jul 2010 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
The objective of these assignments is to teach the students about crystal lattices and Miler indices for planes and directions.
Crystal Viewer Lab Exercise
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 Directions and Miller Indices
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...
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...
