This applet provides an interactive picture of diamond and zincblende structures that allows students to view a simple cubic cell from any perspective. This is an important tool for helping students picture the placement of atoms along various crystallagraphic lines and planes.
A wide range of group IV, III-V, and II-VI semiconductors can be viewed.
An impressive collection of data about each of the materials is given. This includes, for example, density, carrier effective masses, dielectric constant, optical phonon energy, etc.
