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 selflearning 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...

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 Viewer Tool Verification (V 2.3.4)
15 Jun 2010  Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This text verifies the Crystal Viewer Tool by comparing the amount of dangling bonds at the silicon surface for [100], [110] and [111] crystal orientation. The crystal viewer results are in agreement with experimental findings.

Crystal Structures  Packing Efficiency Exercise
15 Jun 2010  Contributor(s):: Dragica Vasileska, Gerhard Klimeck
Consider the most efficient way of packing together equalsized spheres and stacking closepacked 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...

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...

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...

ABINIT: FirstTime User Guide
09 Jun 2009   Contributor(s):: Benjamin P Haley
This firsttime user guide provides an introduction to using ABINIT on nanoHUB. We include a very brief summary of Density Functional Theory along with a tour of the Rappture interface. We discuss the default simulation (what happens if you don't change any inputs, and just hit "simulate") as...
