@vzn, could you elaborate?

Q: Can electron conductance be decomposed into local flows (be seen as driven diffusion)?

Jarek DudaImagine attaching electrodes to a complex sample, e.g. a semi-conductor or a single chemical molecule, leading to some electric current. Can we decompose this electron flow into local flows? - like imagine locally attaching amperometer and counting what fraction of electrons flow e.g. between g...

@vzn, thanx ... I haven't noticed that it was deleted ...
Maybe I will try again in a week or two as just e.g. "How electric field is glued in the center of electron to avoid infinite energy?"
Let's see what will happen with the today's one ...
Electron conductance is in intersection between QM and diffusion - and MERW allows to understand and repair the disagreement of standard diffusion models
Complete quantum calculations of conductance cannot handle even simple molecules
In contrast, MERW is quite accessible, still having some quantum properties
The question is how good this approximation is?
It neglects interference - how important interference is in conductance?
This is extremely important topic in the times of processors with transistors of size of a few atoms ... but also extremely difficult ...

@Jarek endorse your efforts (+1 etc) but Physics (or other SE sites in general) is just not that great for cutting edge physics/ science, somewhat by intention/ design. its largely Phds answering the questions of undergraduates. Phds have no one but themselves to answer their own questions. thats the nature of research :)

I know, the same with physicsforums (also faculty)
the problem are ignored question - thought provoking I am trying to initiate
but most of them are immune :/
