Why conventional GITT fails; how to fix it
We explain why conventional GITT (Galvanostatic Intermittent Titration Technique) measurements do not work as intended.
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.
Calculating Seebeck-Conductivity relations
Wondering how to fit Seebeck-conductivity relations to your data? Is there an explicit equation?
T2 Resistivity in Perovskites
Elongated Fermi surfaces in perovskites like SrTiO3 explain the T2 resistivity, previously thought to be from electron-electron interactions/scattering.
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.
