Bending and pinching of three-phase stripes: From secondary instabilities to morphological deformations in organic photovoltaics
Alon Z. Shapira, Nir Gavish, Hannes Uecker +1
Optimizing the properties of the mosaic morphology of bulk heterojunction (BHJ) organic photovoltaics (OPV) is not only challenging technologically but also intriguing from the mec…
Ginzburg-Landau model of a Stiffnessometer -- a superconducting stiffness meter device
Nir Gavish, Oded Kenneth, Amit Keren
We study the Ginzburg-Landau equations of super-conductivity describing the experimental setup of a Stiffnessometer device. In particular, we consider the nonlinear regime which re…
Large deviations and gradient flows for the Brownian one-dimensional hard-rod system
Nir Gavish, Pierre Nyquist, Mark Peletier
We study a system of hard rods of finite size in one space dimension, which move by Brownian noise while avoiding overlap. We consider a scaling in which the number of particles te…
Pattern formation aspects of electrically charged tri-stable media with implications to bulk heterojunction in organic photovoltaics
Alon Z. Shapira, Nir Gavish, Arik Yochelis
A common thread in designing electrochemically-based renewable energy devices comprises materials that exploit nano-scale morphologies, e.g., supercapacitors, batteries, fuel cells…
The nature of the phase transition in the cuprates as revealed by a magnetic field free stiffness meter
Itzik Kapon, Zaher Salman, Thomas Prokscha +2
A new method to measure the superconducting stiffness tensor , without subjecting the sample to magnetic field, is applied to LaSrCuO (LSCO).…
Finite domain effects in steady-state solutions of Poisson-Nernst-Planck equations
Doron Elad, Nir Gavish
Steady-state solutions of the Poisson-Nernst-Planck model are studied in the asymptotic limit of large, but finite domains. By using asymptotic matching for integrals, we derive an…
