A substance that is usually a solid element or a compound that can conduct electricity under certain conditions that makes it a good medium for passing current is known as a semiconductor.
Insulators, semiconductors and conductors.
Semiconductors are the materials that are conductive between an insulator that are non-conductors and metals that are conductors. They can either be pure element or even compounds. They’re an important part of our lives due to the role played by them in electronic devices.
- Solid-state physics have classified the material that exists in nature into three types- Insulators, semiconductors and conductors.
- The material with fully occupied valence bands and empty conduction bands are insulators. The material with an almost filled valence band and almost empty conduction band are semiconductors. In contrast, the material with an empty conduction band and filled conduction band are conductors.
