Electric Field Effect on Quantum Well

[kpsr]

Hello everybody !

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

Thanks for any Help.

The application of a constant electric field makes it so that the bottom of the quantum well is slanted, but the sides remain vertical.

I couldn't comment on how the density of states would change, except to say that above a certain energy (larger than the tall side of the slant) I think the density of states should have the same functional form as the regular 1D box.

Thanks for your reply, Please check this Slide's 9th page,
there we can see step like 2-d density of states (DOS) merging to form 3-D DOS under bias.
