SUMMARY

The discussion centers on the impact of interfaces on electronic transport in coherent devices, specifically when the device length is shorter than the phase relaxation length. It concludes that the non-uniform electron distribution across the interface acts as a scatterer, leading to level broadening in the vicinity of the interface. Participants suggest utilizing Google Scholar to find relevant articles and references that explore this phenomenon further.

PREREQUISITES
  • Understanding of coherent electronic transport
  • Familiarity with phase relaxation length concepts
  • Knowledge of electron distribution and scattering mechanisms
  • Experience with academic research tools like Google Scholar
NEXT STEPS
  • Research "coherent electronic transport in nanostructures"
  • Explore "phase relaxation length in quantum devices"
  • Investigate "electron scattering at interfaces"
  • Review literature on "level broadening in semiconductor physics"
USEFUL FOR

Researchers, physicists, and engineers working in the fields of quantum mechanics, semiconductor physics, and electronic device design who are interested in the effects of interfaces on electronic transport properties.

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.
