Question: What is the primary mechanism of current flow in semiconductors?

Options:

Correct Answer: Both electron and hole flow

Solution:

Current flow in semiconductors occurs due to the movement of both electrons and holes.

What is the primary mechanism of current flow in semiconductors?

What is the primary mechanism of current flow in semiconductors?

Step 1: Understand that semiconductors are materials that can conduct electricity under certain conditions.
Step 2: Know that in semiconductors, there are two main types of charge carriers: electrons and holes.
Step 3: Electrons are negatively charged particles that can move through the semiconductor.
Step 4: Holes are the absence of electrons and can be thought of as positive charge carriers.
Step 5: When an electric field is applied, electrons move towards the positive side, and holes move towards the negative side.
Step 6: The movement of both electrons and holes together creates an electric current in the semiconductor.
