In an Intrinsic semiconductor, current conduction is due to ……..Select one:a.Holes and electronsb.only holesc.None of the answersd.Only electrons

Break Down the Problem

1. Identify the types of charge carriers in an intrinsic semiconductor.
2. Consider the conduction mechanisms in semiconductors.

Relevant Concepts

• Intrinsic semiconductors have equal numbers of electrons and holes.
• Electrons are negatively charged charge carriers, while holes can be considered positive charge carriers.

Analysis and Detail

1. In an intrinsic semiconductor, charge carriers are generated when electrons gain enough energy to jump from the valence band to the conduction band.
2. Each electron that leaves the valence band creates a hole, leading to both types of charge carriers being present and contributing to current conduction.

Verify and Summarize

• Since both holes and electrons are fundamental to current conduction in intrinsic semiconductors, the correct answer can be confirmed.

Final Answer

The correct answer is: a. Holes and electrons.
