  3. AIDA: A tool for exhaustive enumeration of solutions to the quantized Frank-Bilby equation

    08 Jan 2018 | | Contributor(s):: Ali Sangghaleh, Michael J. Demkowicz

    We present a tool called Arrangement of Interface Dislocation Arrays (AIDA) for enumerating all dislocation networks that satisfy the quantized Frank-Bilby equation for any interface between cubic crystals with a single-atom basis, i.e. FCC/FCC, BCC/BCC, and FCC/BCC interfaces. The set of...

  5. Crystal Structures

    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...

  6. Crystal Structures - Packing Efficiency Exercise

    15 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...

  7. Crystal Viewer 2.0

  8. 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...

  17. Modern X-ray Scattering Methods for Nanoscale Materials Analysis

    15 Oct 2008 | | Contributor(s):: Richard J. Matyi

    Since its discovery by von Laue in 1912, X-ray diffraction has become an indispensable tool for structure determinations in the physical and biological sciences. X-rays are characterized by high energies and by wavelengths that are commensurate with nanometer-sized structures – unlike optical...
