The mobility concept in charge transport: pitfalls
Did you know that mobility can be a misleading metric in understanding charge transport? We explain the pitfalls of Drude mobility.
Force, Flux, and Irreversible Processes
Introduction to generalzied driving force (affinity) and flux for non-equilibrium thermodynamics. Entropy production and local equilibrium.
Types of Diffusivities
Why is chemical diffusivity similar to defect diffusivity, not self-diffusivity? How's tracer diffusivity related? Here's a guide to diffusion coefficients.
Fick’s Law: Thermodynamic Origin
Using the generalized thermodynamic driving force, we find where the definition of diffusivity comes from.
