1. Crystal Viewer Lab Exercise

   Teaching Materials | 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...

2. Crystal Viewer Tool Verification (V 2.3.4)

   Teaching Materials | 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.

3. Crystal Structures - Packing Efficiency Exercise

   Teaching Materials | 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...

4. Crystal Structures

   Teaching Materials | 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...

5. Illinois ECE 440: Introduction to Crystal Properties Homework

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

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

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

   Online Presentations | 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...

8. Exercise: Crystal Lattices

   0.0 out of 5 stars 

   Teaching Materials | 29 Jul 2008 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck

   This exercise helps the student better understand various types of crystal lattices, in particular diamond and zinc-blende and also helps in better understanding of the miller indicies. The results to some of these problems can be easily arrived at by using the crystal viewer...

9. Illinois Physics 498: Introduction to Biological Physics

   0.0 out of 5 stars 

   Courses | 07 Apr 2008 | Contributor(s):: Paul R Selvin

   We will apply simple yet powerful ideas of physics to gain some understanding of biology. (What is the inertia of a bacteria and how does this affect its behavior?) We will begin with atoms, move to molecules, then macromolecules, then cells, and finally whole systems. For example, how do we...

10. Homework Exercise on Bravais Lattices, Crystal Structures, Miller Indices

    Teaching Materials | 30 Mar 2008 | Contributor(s):: Abhijeet Paul, Gerhard Klimeck

    The tutorial questions based on Crystal Viewer Lab v1.0 available online at Crystal Viewer Lab. Students are asked to explore different Bravais lattices, crystal structures, and Miller indices. Reference / course book: Semiconductor Device Fundamentals by Robert E. PierretNCN@Purdue

11. Spectroscopy and Modeling to Infer Channel Structure and Function

    0.0 out of 5 stars 

    Online Presentations | 23 Mar 2008 | Contributor(s):: Vishwanath Jogini

    We are particularly interested in issues about ion permeation, ion selectivity, gating, and channel inhibitors. We are currently working on the KcsA channel, the OmpF porin, and the gramicidin A> channel. We are also spending our efforts in the development of new computational approaches for...
