In MOSFET at strong inversion electrons confined to triangular quantum well, electrons occupy only 1 or 2 lowest subbands.

and the Van Dort model gives the quantum mechanical intrinsic carrier density in inversion channel via increased energy band-gap(ΔE).

**N**

_{QM}**=**

**N**this carrier amount is very high.

_{CL}× Exp^{(-ΔE/2kt)}But density of states for inversion charges in subbads reduced from the higher 3-D density to the lower 2-D density.

Then still HOW the above Van Dort's formula giving that high amount of charge..?

Thank You.
