Failure of the nernst-einstein equation in mixed conductor compounds

摘要

The conventional Nernst-Einstein equation inherently presupposes that the charge carriers of different ytpes migrate independently of each other. It is, thus, readily expected that the equation is to fail if the charge carriers interfere with each other upon their transfer. We have recently found that in mixed ionic electronic conductor compounds, mobile ions are itnerfering with electrons upon their migration and that that electron/ion interference leads to the breakdown of the conventionla Nernst-Einstein equation. We will present the experimental evidences for the breakdown of the conventional equation.
