Semiconductors

Semiconductors are materials that have electrical conductivity between that of a conductor and an insulator. They are typically made from elements like silicon or germanium and exhibit unique electronic properties that can be manipulated by adding impurities through a process known as doping. This ability to control their electrical properties makes semiconductors essential for modern electronics. They can conduct electricity under certain conditions but not others, allowing them to function as switches or signal modulators in electronic devices. Semiconductors are the foundational components in a wide range of technologies, including transistors, diodes, and integrated circuits, which are used in devices such as computers, smartphones, and various consumer electronics. Their versatility and efficiency in controlling electrical current are key to advancements in electronics and technology.
