Introduction:
Schottky diodes are a type of diode that use a metal-semiconductor junction instead of a p-n junction. They are known for their fast switching speed and low forward voltage drop. In this response, we will discuss the false statement regarding Schottky diodes and explain why it is incorrect.

False Statement:
The false statement regarding Schottky diodes is option 'C': The majority charge carriers in a Schottky diode are holes.

Explanation:
To understand why this statement is false, we need to first understand the basic operation of a Schottky diode and the charge carriers involved.

Schottky Diode Operation:
A Schottky diode is formed by a metal-semiconductor junction, typically using a metal like aluminum (Al) on a semiconductor material like silicon (Si). The metal acts as the anode, and the semiconductor acts as the cathode. When a forward bias voltage is applied, the metal injects electrons into the semiconductor, creating a conductive path for current flow.

Charge Carriers in Schottky Diodes:
In a Schottky diode, the majority charge carriers are the electrons. When a forward bias voltage is applied, the electrons from the metal move into the semiconductor and become the majority charge carriers responsible for the current flow. The semiconductor material (e.g., silicon) used in Schottky diodes is an N-type material, meaning it has excess free electrons.

Comparison with P-N Junction Diode:
In a p-n junction diode, the majority charge carriers depend on the type of doping in the semiconductor material. In an N-type material, like the semiconductor used in Schottky diodes, the majority charge carriers are electrons. However, in a P-type material, the majority charge carriers are holes. Therefore, the statement that the majority charge carriers in a Schottky diode are holes is incorrect.

Correct Option:
The correct option is 'C': The majority charge carriers in a Schottky diode are holes.

Conclusion:
In conclusion, Schottky diodes have a metal-semiconductor junction and the majority charge carriers in a Schottky diode are electrons, not holes. This false statement can be misleading and it is important to have a clear understanding of the operation and characteristics of Schottky diodes.
