Level Broadening at interfaces

[collpitt]

Dear all,
I have a question regarding electronic transport in a device with length smaller than the phase relaxation length.
Consider a coherent device with an interface in the middle. The interface would act as a scatterer and the electron distribution across the interface would be non-uniform. Will this non-uniform distribution dictate a level broadening near the vicinity of the interface?

Please answer the question/post some references!

Thank you

I should think that it would.

You should be able to find articles/references with appropriate queries via Google Scholar.
