Hello to all !
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).
NQM = NCL× Exp(-ΔE/2kt) this carrier amount is very high.
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..?0
Electric Field Effect on Quantum Well.

Recently i heard that, application of an electric field onto a quantum well tilts the quatum well
and changes its 2-D density of states to 3-D bulk density. Is this true..?
Can any body give some more information or reference on this..?
