Title: electrochemical potentials of electrodes in two terminal device
Post by: jerry on October 29, 2011, 04:24

Dear,
    When i calculate a two probe system, i find that the electrochemical potentials of electrodes shown in the transmission spectrum are the Fermi level of electrodes plus and minus 0.5*the applied voltage no matter how the left electrode voltage or right electrode voltage is set. Is this so?

That's correct, because it's only the difference in voltage (the actual applied bias) that matters.
