Question

Which type of extrinsic semiconductor is formed when silicon is doped with Bismuth

Answer 1

Explanation:

Silicon is doped with Bismuth?

i) Germanium belongs to group 14 whereas Indium belongs to 13th group.

Hence, they together form a p-type semiconductor.

Answer 2

P type of extrinsic semiconductor is formed when silicon is doped with bismuth.

• A p-type extrinsic semicondutor is formed when we dope a normal semiconductor by an acceptor atom. (Acceptor atom is a type of atom which can accept multiple electrons)

• Similarly,the silicon is a normal semiconductor and the bismuth is an acceptor atom (due to it's 6S2 6P3 electronic configuration).

• That's why a p-type extrinsic semicondutor will be produced when silicon is doped with bismuth.
