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
Verified Correct Answer: C.
Physical Principles & Numerical Solution
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
