Dear developers and users,
I am trying to calculate the spin polarized current flowing
through magnetic junction MoS2/graphene/MoS2 with Co as electrodes (
https://journals.aps.org/prb/abstract/10.1103/PhysRevB.103.165407). For the
spin up current (parallel to both Co electrode's spins), the transmission
function seems to retain its feature with increasing value of
TBT.Contours.Eta, but the transmission function for spin down current
varies greatly with it.
Does this imply my calculation with transiesta is actually problematic? Or
is it normal to use an Eta as large as 100 meV in order to get converged
results for tbtrans calculation?
I had attached the figures for transmission functions, and also input files
for the calculation.
Thank you for your attention.
