A semiconductor is a material that has electrical conductivity between a conductor and an insulator. Commonly made from silicon, semiconductors are crucial in modern electronics. They can control electrical current, making them essential for devices like diodes, transistors, and integrated circuits. By adding impurities, a process called doping, their conductivity can be precisely adjusted. This capability allows for the development of complex electronic devices such as computers, smartphones, and solar cells. Semiconductors can amplify and switch electrical signals, which has driven advancements in technology, transforming communication, computing, and energy industries. Their unique properties make semiconductors fundamental to the functionality and innovation of countless electronic devices.
