<h3>What is a semiconductor?</h3>
A semiconductor is a device whose conductivity lies between the conductivity of the conductors and the insulators.
Due to the inclusion of an impurity or temperature effects, a solid substance with conductivity between that of an insulator and that of most metals. Semiconductor devices, particularly silicon devices, are key components of most electronic circuits.
