If silicon is doped with phosphorus, what type of semiconductor material will be formed?
Zener material
P-n junction
n-type
p-type
توضيح
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
