Semiconductors

Semiconductors are materials that have electrical conductivity between that of a conductor (like copper) and an insulator (like glass). Their conductivity can be altered and controlled by introducing impurities (doping) or applying an electric field. This unique property makes them crucial components in modern electronics, allowing for the creation of transistors, diodes, and integrated circuits. semiconductors form the building blocks of computers, smartphones, and countless other devices. They are typically crystalline solids like silicon and germanium.
