A semiconductor is a conductive substance that acts as an intermediate layer between a conductor and an insulator. Semiconductors act as insulators at low temperatures and conduct electricity at room temperatures. They are called "semiconductors" because the substance can conduct electricity in some conditions and not in others. It changes in the presence of semiconductor impurities, and different impurities can give different semiconductor properties. When two different semiconductors combine, a knot is formed.
