If silicon is doped with phosphorus; what type of semiconductor material will be formed?

A. Zener material
B. P-n junction
C. n-type
D. p-type

Correct Answer:

Option C = n-type

Explanation

When silicon is doped with a trivalent atom. A p-type semi-conductor will be formed when silicon is doped with a pentavalent atom such as arsenic, a n-type semi-conductor will be formed. Phosphorous is a pentavalent element, so it will produce a o -type semi-conductor
