Answer
A semi-conductor is a material that has electrical conductivity that falls between that of a conductor and an insulator. Unlike good conductors such as metals, semi-conductors do not effortlessly conduct electricity. However, they have the unique ability to conduct electricity under certain conditions, typically when exposed to heat or light.
This means they can be modified to perform various functions in electronic devices.
