In a semiconductor, the current conduction is due to:
Open in App
Solution
The correct option is C circuit 3 and circuit 1
In a semiconductor, the current conduction is due to holes and free electrons. n-type semiconductor is doped with a pentavalent impurity to create free electrons. Such a material is conductive. The electron is the majority carrier. p-type semiconductor, doped with a trivalent impurity, has an abundance of free holes. These are positive charge carriers. The p-type material is conductive. The hole is the majority carrier.
