Conductors, semiconductors, and insulators are three types of materials. Semiconductors are those materials whose conductivity lies between that of conductors and insulators. Most electronic devices are based on semiconductors. At absolute zero(0°K) temperature, the semiconductors behave as insulators. As temperature increases, the conductivity increases. In the old days, only vacuum tubes were used. But nowadays …
