Hi,
I would like to do an electron transport analysis using the transmission eigenstates tool in VNL.
I have the following two questions regarding the isosurface plot option for the eigenstates.
(1) For choosing the isovalue, should I choose the isovalue = the eigenvalue that I am interested in? e.g. I have a eigenvalue = 0.5, I should choose the isovalue = 0.5?
I checked this tutorial page and it seems to say so. https://docs.quantumatk.com/manual/Types/TransmissionEigenstate/TransmissionEigenstate.html#transmissioneigenstate-c
(2) The phase of the eigenstates is expressed using a color legend, what does the phase of the eigenstates mean? Does it have anything to do with the transmission contribution? How to interpret it physically?
Any help is appreciated! Thank you in advance.
