In this lecture you will learn about Carbon Allotropes and the Band Theory of Solids. First you will cover the intricacies of Diamond and Graphite which all emerge from the Carbon atom. Next you will cover C-60 which is an unexpected Allotrope also known as the Buckyball after R. Buckminster Fuller. Following the Buckyball, you will cover the possible uses of Carbon Nanotubes before moving into Metals, Insulators, and Semiconductors that make up the three Classes of Conductors. Next you will investigate Conductivity and Band Theory with an example of the Valence Band. P-Type and N-Type Semiconductors and Doping Techniques are discussed next before looking at the birth of the Integrated Circuit with the P/N Junction. Lastly, you will learn about Glasses and Ceramics.
large crystals MOs combine to give bands; valence band; conduction
of insulator like Si with P gives n-type semiconductor
of Si with Al gives p-type semiconductor
junctions yield transistors and chips
common ones made from quartz, sodium carbonate, calcium oxide;
