Question

Semiconductors are derived from compounds of

• A. p-block elements
• B. intrinsic semiconductor
• C. mixed conductor
• D. extrinsic semiconductor

Hint:

Group 14 (Si, Ge) → backbone of semiconductor physics.

Answer 1

The Correct Option is A

Concept: Semiconductors have conductivity between conductors and insulators.

Step 1: Identify common semiconductor elements. Si and Ge belong to Group 14 (p-block).

Step 2: Consider compound semiconductors. GaAs, InP, CdS — combinations of p-block elements.

Step 3: Eliminate other options. Intrinsic/extrinsic refer to types, not source; mixed conductor is unrelated.
