The Inversion Layer Is a Channel of an Endoped Region

A current needs to be a circular flow of electrons or charges, all in the same direction. In order to have a current flowing, we need to form ation of what's called a channel - an inversion layer. Normally there is no such inversion layer normally, yoe've just got the p doped regionThere are more mobile posit charges than mobile negative charges. If you apply apos voltage to the gate, that gets mediated through the insulator and is felt in the well under the gate. This positive potential attracts electrons to it because electrons tend to move towards positive charges. You've got a positive potential herea negatively charged electrons will move towards it. So if we can
