What is a Semiconductor?
A semiconductor is a crystalline material that possesses an
intermediate electrical conductivity value between that of an
insulator and a conductor. These materials have an electrical
current resistance that is lower in one direction than the other.
Elemental semiconductors include silicon (Si) and germanium (Ge); however impurities can be intentionally added to create compound semiconductors pcb, thereby altering the conductive properties. This process is known as semiconductor doping.
Silicon is the most common base material of doped or extrinsic semiconductors. Like germanium, silicon possesses 4 valence electrons in its outer orbital shell, which allows it to make strong covalent bonds. This property actually puts silicon more in line with typical insulators due to the low number of electrons available to facilitate conduction, but this can be adjusted through the addition of dopants.
