WebMay 4, 2011 · The plan of the paper is as follows. Section 2 contains the general relation between mobility and the diffusion matrix for Langevin dynamics in a magnetic field plus other general external forces. The correction to the Sutherland–Einstein relation is given in terms of a correlation function between the particle velocity and the applied forces.

WebThe so-called Einstein relation links the mobility to the diffusion constant. This relation is usually derived considering that the total particle flux or current must vanish in thermal equilibrium [7–11]. Indeed, if the total current is null, then µcF −D ∂c ∂x = 0. (3) This equation can be expressed as [12] µ =− D c ∂c ∂V, (4) WebDec 15, 2014 · In this work, the Einstein relation between the diffusivity and mobility of charge carriers for disordered organic semiconductors is analyzed. We formulate an analytic theory that allows predicting the Einstein relation for charge carrier hopping in disordered organic semiconductors with Gaussian density of states distribution as a function of … terabit to megabit
