  13. Crystal Directions and Miller Indices

    04 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...

  15. Crystal Structures

    04 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...

  16. Crystal Structures - Packing Efficiency Exercise

    14 Jun 2010 | | Contributor(s):: Dragica Vasileska, Gerhard Klimeck

    Consider the most efficient way of packing together equal-sized spheres and stacking close-packed atomic planes in three dimensions. For example, if plane A lies beneath plane B, there are two possible ways of placing an additional atom on top of layer B. If an additional layer was placed...

    This video shows the use of the Crystal Viewer Tool to visualize several crystal systems, including Si, GaAs, C60 Buckyball, and a carbon nanotube. Crystal systems are rotated in 3D, zoomed in and out, and the lattice style changes from sticks and balls to lines to spheres.

  20. 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...
