The impedance of a charged flat-plate electric double-layer capacitor
Adrian L. Usler, David Fertig, Mathijs Janssen
We calculate the impedance of a flat-plate electric double-layer (EDL) capacitor by means of Finite Element Method simulations of modified Poisson--Nernst--Planck equations. In Nyq…

Basic requirements for potential differences across solid--fluid interfaces
David Fertig, Adrian L. Usler, Mathijs Janssen
At model water--vapor and water--solid interfaces, molecular ordering leads to charge oscillations and, thereby, to a spatially varying electrostatic potential. Atomistic simulatio…

Charging dynamics of electric double layer capacitors including beyond-mean-field electrostatic correlations
David Fertig, Mathijs Janssen
Electric double layer (EDL) formation underlies the functioning of supercapacitors and several other electrochemical technologies. Here, we study how the EDL formation near two fla…
