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 is C

 

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
