Teaching Materials (1-13 of 13)

  1. Crystal Structure

    11 Jul 2011 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck

    This set of lecture notes describe crystalline structure and different types of crystal lattices.

  2. 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...

  3. 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...

  4. 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.

  5. 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...

  6. 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...

  7. 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...

  9. Illinois ECE 440: Introduction to Crystal Properties Homework

    28 Jan 2010 | | Contributor(s):: Mohamed Mohamed

    This homework Assignment covers basic introduction to Material Properties and Crystal Structures.

  10. ABINIT: First-Time User Guide

    09 Jun 2009 | | Contributor(s):: Benjamin P Haley

    This first-time 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...
