Basic ElectronicsSemiconductor I Materials that permit flow of electrons are called conductors ( , gold, silver, copper, etc.). Materials that block flow of electrons are called insulators ( , rubber, glass, Teflon, mica, etc.). Materials whose conductivity falls between those of conductors and insulators are called semiconductors. Semiconductors are part-time conductors whose conductivity can be II Silicon is the most common material used to build semiconductor devices. Si is the main ingredient of sand and it is estimated that a cubic mile of seawater contains 15,000 tons of Si. Si is spun and grown into a crystalline structure and cut into wafers to make electronic III Atoms in a pure silicon wafer contains four electrons in outer orbit (called valence electrons).
