General Questions and Answers / What's the difference of Small electrode and Big electrode ?
« on: November 22, 2009, 04:19 »
Dear, I have one question:
We test the I-V of the center region, If we chose different electrodes, we will get different answers. For example lih2li modle, we want to get the I-V of H2, so we can use the single Li atom as the electrode as the example said ,and we can also use a big Au(3*3) electrode, different electrodes will get different answers cost different calculation time.
which one is better ?
Thank you.
