The correct answer is: A. Minority carrier device
A MOSFET (metal-oxide-semiconductor field-effect transistor) is a type of transistor that uses a voltage to control the flow of current between two terminals. It is a minority carrier device, which means that it relies on the movement of minority carriers (electrons in a P-type semiconductor, or holes in an N-type semiconductor) to conduct current.
MOSFETs are used in a wide variety of electronic devices, including computers, cell phones, and power supplies. They are one of the most common types of transistors, and are often used in place of bipolar transistors because they are more efficient and have a higher switching speed.
Here is a brief explanation of each option:
- A. Minority carrier device
A minority carrier device is a semiconductor device that relies on the movement of minority carriers (electrons in a P-type semiconductor, or holes in an N-type semiconductor) to conduct current. MOSFETs are minority carrier devices.
- B. Majority carrier device
A majority carrier device is a semiconductor device that relies on the movement of majority carriers (electrons in an N-type semiconductor, or holes in a P-type semiconductor) to conduct current. Bipolar transistors are majority carrier devices.
- C. Majority & minority carrier device
A majority & minority carrier device is a semiconductor device that relies on the movement of both majority and minority carriers to conduct current. Junction field-effect transistors (JFETs) are majority & minority carrier devices.
- D. None of the mentioned
None of the mentioned options are correct.
