In the world of technology today, the best known semiconductor is silicon. It is at the heart of any electronic device. Semiconductors are materials having electrical conductors and insulators. They behave like insulators when cold. But under higher temperatures or light with the addition of impurities, their conductivities increase dramatically, reaching levels that may approach those of metals.
