The explanation is as follows
Semiconductors are materials that have electrical conductivity between conductors such as most metals and non-conductors or insulators like ceramics. How much electricity a semiconductor can conduct depends on the material and its mixture content. Semiconductors can be insulators at low temperatures and conductors at high temperatures. As they are used in the fabrication of electronic devices, semiconductors play an important role in our lives.
