P n Junction Diode Basics Quiz

P-N Junction Diode

• A P-N junction diode is formed by combining two types of semiconductor materials, p-type (positive) and n-type (negative), creating a junction.

Characteristics

• Forward bias occurs when the positive terminal of the battery is connected to the p-type material and the negative terminal is connected to the n-type material.
• In forward bias, the depletion region is reduced, and the diode becomes less resistive, allowing current to flow.

Depletion Region

• The depletion region is a narrow region at the P-N junction where the electrons and holes combine, leaving no charge carriers.
• The role of the depletion region is to act as a barrier to the flow of charge carriers, controlling the flow of current.
