Semiconductor Electronics : Materials, Devices and Simple Circuits

  1. Which of the following, when added as an impurity, into the silicon, silicon, produces n-type semi-conductor?
    1. Phosphorous
    2. Aluminium
    3. Magnesium
    4. Both b and c
Correct Option: A

Phosphorous (P) is pentavalent and silicon is tetravalent. Therefore, when silicon is doped with pentavalent impurity, it forms a n-type semiconductor.
