Majority Carriers in n-channel MOSFET
There are primarily two types of charge carriers in a semiconductor material - electrons and holes. In an n-channel MOSFET, the majority carriers are electrons.

Explanation

n-channel MOSFET
- An n-channel MOSFET is a type of metal-oxide-semiconductor field-effect transistor where the channel is doped with electron carriers.
- When a positive voltage is applied to the gate terminal, it creates an electric field that attracts electrons from the source terminal towards the channel region.

Electron as majority carriers
- In an n-channel MOSFET, the majority carriers are electrons because the channel region is doped with donor impurities (e.g., phosphorus) that provide extra electrons.
- These electrons are free to move within the channel when a voltage is applied, allowing the current to flow from the source to the drain terminal.

Importance of majority carriers
- The majority carriers play a crucial role in determining the conductivity and performance of the n-channel MOSFET.
- By controlling the number and mobility of electrons in the channel, the MOSFET can be used for various applications in digital and analog circuits.
Therefore, in an n-channel MOSFET, the majority carriers are electrons, which are responsible for the conduction of current in the device.
