How to View (100), (110) and (111) Planes in Silicon Using Crystal Viewer 3.0
24 Mar 2017 | Contributor(s): Tanya Faltens
This is a step-by-step guide that describes how to draw planes through a structure, and then view the structure, cut by the planes.This exercise may be helpful to understand the different symmetries observed on different planes in Si, and the different oxidation rates for different faces.
Visualizing Crystal Structures: An interactive group classroom activity
11 Nov 2016 | Teaching Materials | Contributor(s): Susan Gentry, Tanya Faltens
OverviewThis learning activity guides students through the visualization of three-dimensional crystal structures using the software package Ovito. Students work in groups manipulating crystal structures on their personal computers, ranking the planar densities of the (100), (110), and...
How to Create Atomic Planes in FCC, NaCl and Simple Cubic Structures
27 Oct 2016 | Teaching Materials | Contributor(s): Tanya Faltens
This step by step guide shows how to create atomic planes in some common crystal structures. The crystal structures can be sliced along the planes, and the atomic packing of each plane investigated. Links to saved simulations of each of the planes and structures are included. These instructions...
