025 - Covalent Network Solids

In this video Paul Andersen explains how covalent network solids form elementally (like graphite) or by combining multiple nonmetals (like quartz). Covalent network solids contain elements from the carbon group because they have four valence electrons and can create three-dimensional shapes. Silicon crystals act as semiconductors and can be either n-type or p-type doped to increase their effectiveness.
