Semiconductor

A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator. This property allows it to control electrical current and make it possible for semiconductors to be used in various electronic devices. Semiconductors can be elemental materials, like silicon and germanium, or compound materials, such as gallium arsenide.The conductivity of a semiconductor can be modified by the introduction of impurities through a process called doping, enabling the creation of p-type and n-type semiconductors. These modifications create regions of positive and negative charge carriers, which are fundamental for various electronic applications.Semiconductors are the backbone of modern electronics, being essential components in devices such as transistors, diodes, and integrated circuits. Their ability to switch between conductive and non-conductive states makes them crucial for digital computing and signal processing.
