1. What is MOSFET and how does it work?
MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor), that is, metal-oxide-semiconductor field effect transistor, is a transistor that uses electric field effect to control conduction and shutdown. MOSFET controls the flow of current between the source and drain by applying voltage to the gate. Its working principle is as follows:
Working principle:
When a positive voltage is applied to the gate, the electric field causes the impurities in the substrate to form an "open" n-type or p-type conductive area, i.e., a channel, between the gate and the substrate. A capacitor is formed between the oxide layer above the channel and the gate, called the gate capacitance. When the channel conductive area extends to the source and drain, the MOSFET is in the on state. In the on state, the voltage difference between the source and the drain drives the current to flow through the conductive area.
When a negative voltage is applied to the gate, the channel on the substrate shrinks, the conductivity weakens, and the current between the source and the drain decreases. When the gate voltage continues to decrease, the channel eventually disappears, the MOSFET is in the off state, there is no conductive path between the source and the drain, and the MOSFET is in a high-resistance state.

3. Is MOSFET a transistor?
MOSFET is a type of transistor. MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a metal oxide semiconductor field effect transistor, which is a type of field effect transistor.
Basic concepts and characteristics of MOSFET
MOSFET is an insulated gate field effect transistor that mainly controls the conductive channel between the source and the drain through the gate voltage. Its working principle is to apply voltage to the gate to form an electric field, thereby controlling the charge distribution on the surface of the semiconductor and thus controlling the flow of current. MOSFET has the advantages of high input impedance, low noise, and good frequency characteristics, and is widely used in analog circuits and digital circuits.
