In this lecture we look at the band structure of several p-block elements that crystallize with structures that have a face centered cubic Bravais lattice. We start with aluminum, which has a cubic close packed structure, and then move onto the group 14 elements with the diamond structure (carbon, silicon, germanium and gray tin). Along the way we study the bonding fundamentals that differentiate metals, semiconductors and insulators. This lecture was designed and delivered by Patrick Woodward for use in the course Solid State Chemistry (Chem 7330) at Ohio State University.
