A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator, making it essential for modern electronics. Semiconductors can be modified by adding impurities (doping), allowing them to conduct electricity under certain conditions, which is crucial for various applications in electronic devices such as diodes and transistors. Their unique properties enable the generation and manipulation of electron-hole pairs, which play a vital role in the functioning of many electronic components.
