When a negative voltage is appleid on the gate, the electrons underneath the sulfur oxide respond to the flow of current and get pushed downwards into the substrate.
Unlike the N-channel, the drain and the source are doped with p+ impurity while the substrate is in n-type.
When a positive voltage is applied on the gate, the electrons from the n+ source and the drain region are attracted towards it, forming an electron reach channel.
The current flows through the P-channel MOSFET.
The drain and the source are doped with n+ impurity while the substrate is in p-type.
When voltage is applied at the gate, the conductivity of the device increases.
When there’s no voltage applied at the gate, there’s no conductance.
Enhancement mode tends to be referred to as a normally open switch, where for conductance to occur, voltage is needed to pass-through.
When voltage is applied at the gate, The conductivity of the device decreases.
It states that when there’s no voltage applied at the gate, channel conductance is at its maximum.
Depletion mode tends to be referred to as a normally closed switch.
Here are its explanation, alongside the working principle: Depletion Mode: Each class is available as n-channel or p-channel, tallying up to four types of MOSFETs in total! There are two classes of MOSFETS Depletion Mode, and enhancement mode. The wider the channel region, the better conductivity of a device will be. When voltage is applied at the gate, it generates an electrical field that changes the width width of the channel region, where the electrons flow.
A DC circuit is then formed by connecting a voltage source between these two n-type regions (marked in red).
The gate terminal is then brought out from the thin metallic plate.
A thin insulated metallic plate is then placed on top of the silicon dioxide, acting as a capacitor plate.
The entire surface of the substrate is coated with a layer of silicon dioxide.
The drain terminals (Source and Drain) are then brought out from these two end regions.
Two sides on this p-type substrate are made highly doped with an n-type impurity (marked as n+).
A block, also known as a substrate of p-type semiconductor acts as the base for MOSFET.
