Dear Expert,
I got Transmission spectra for my system (Pics is attached). At any energy points, there are eigen values in the spectrum and if i click that, for even spin up there are two eigen values - spin up and spin down, I don't understand why there are spin up and spin down for even "spindown"
also, I have a stanene nanoribbon having iron cluster on it - How can i find out the HOMO AND LUMO for whole system?
Many thanks
