Question

When the conductivity of a semiconductor is due only to the breaking up of the covalent bonds, the semiconductor is known as:

• A. Donor
• B. Extrinsic
• C. Intrinsic
• D. Acceptor

Hint:

Intrinsic semiconductors are pure materials where electrical conductivity arises due to thermal excitation of electrons.

Answer 1

The Correct Option is C

Step 1: Define intrinsic semiconductors. In intrinsic semiconductors, the conductivity is due to the breaking of covalent bonds, creating free electrons and holes.
Step 2: Conclusion. Thus, when conductivity is due to the breaking up of covalent bonds, the semiconductor is intrinsic.
