Abstract: | A model which used multiple-scattering theory to derive the density dependence of thermal electron mobilities, is employed to do the same for the diffusion coefficient. A surprising consequence of this is that the thermal Einstein relation is not the simple expression that is generally written and never verified, but rather one that depends on the density. |
