What is the fringe effect, in particular for a parallel plate capacitor? What is the result of the effect? And what are we supposed to expect to see with respect to the electric field of the parallel plate capacitor? Especially at the edges? Please help!

If you have two parallel plates forming a capacitor, the electric field does not end abruptly at the edge of the plates. There is some field outside that plates that curves from one to the other. This causes the real capacitance to be larger than what you'd calculate using the ideal formula. You have more electric field because of the fringe fields.

Fringe effect occurs when the electric field extends the area of the overlap.
1. In case of single capacitor, the practical capacitance is greater than the calculated one due to fringe effect.
2. In case of doubling the area of overlap of the capacitor, the fringe effects do not double. Therefore, the practical capacitance is slightly less than the sum of the two individual capacitance.

The fringe-effect is where lines of flux leap from one plate to the next. The effect is greater with higher voltages, and is basically the prelude to arcing, where current litterally leaps from one conductor to another. Here is a site where you can see pictures depicting this phenomenon.

I would think that the fring-effect would lower the said value of the capacitor, as the energy fluxing around the capacitor is an inductive property, although I'm not positive on that one.

it locates between the gate's fringing wall and the drain's or source's elcetron .there is a electric field and can store Q. Another explanation is the tip of some object ,because of its shape ,it can store Q in the tip.
