Title: How to calculate the spin filter or spin-polarized current of a two-probe system
Post by: youngjfly on June 5, 2011, 07:58

How to calculate the spin filter or spin-polarized current of a two-probe system?

When calculating the spin-polarized current, should i have to add an bias?

Thank you very much.

It is obvious that you should apply a bias voltage for the spin-polarized current calculation.

And even also for an unpolarized current.
