Title: Transmission Eigenstates and Pathway
Post by: ams_nanolab on November 16, 2013, 13:53

Dear Sir,

Could you describe how exactly ATK calculates the transmission eigenstates and what significance does the phase of these states have on overall transmittance of the system?

Also in transmission pathway, there's this option of plotting path arrows color coded according to "angle", but for the same transmission direction different arrows have different colors. Does it relate to magnitude ?

No the color is also the angle. The magnitude is the thickness of the arrows.

What if I change the color mode to "Magnitude" ?? .... Will in that case the colors show only the magnitudes of the local transmission between the diff pair of atoms?? What are the meanings of "scaling power", and "threshold" related to this??

Yes. See the tooltips of the various parameters for details.
