Electric double layer of anisotropic dielectric colloids under electric fields
Anisotropic colloidal particles constitute an important class of building blocks for self-assembly directed by electrical fields. The aggregation of these building blocks is driven by induced dipole moments, which arise from an interplay between dielectric effects and the electric double layer. For particles that are anisotropic in shape, charge distribution, and dielectric properties, calculat...
متن کاملWeak localization in electric-double-layer gated few-layer graphene
We induce surface carrier densities up to ∼ ⋅ 7 1014 cm−2 in few-layer graphene devices by electric double layer gating with a polymeric electrolyte. In 3-, 4and 5-layer graphene below 20–30 K we observe a logarithmic upturn of resistance that we attribute to weak localization in the diffusive regime. By studying this effect as a function of carrier density and with ab initio calculations we de...
متن کاملElectrokinetics of concentrated suspensions of spherical colloidal particles with surface conductance, arbitrary zeta potential, and double-layer thickness in static electric fields.
In this paper the electrophoretic mobility and the electrical conductivity of concentrated suspensions of spherical colloidal particles have been numerically studied under arbitrary conditions including zeta potential, particle volume fraction, double-layer thickness (overlapping of double layers is allowed), surface conductance by a dynamic Stern layer model (DSL), and ionic properties of the ...
متن کاملElectric Double Layer Phenomena: A Review on Models and Problems
Electric double layer lies in the heart of modern day electrochemical energy storage devices like batteries, fuel cells, supercapacitors and water filtration membranes. The advent of nanostructured rough and porous electrodes has open new possibilities and new challenges. This review summarizes the theoretical development in the electric double layer theory on porous and rough electrodes. Both ...
متن کاملEffects of image charges, interfacial charge discreteness, and surface roughness on the zeta potential of spherical electric double layers.
We investigate the effects of image charges, interfacial charge discreteness, and surface roughness on spherical electric double layer structures in electrolyte solutions with divalent counterions in the setting of the primitive model. By using Monte Carlo simulations and the image charge method, the zeta potential profile and the integrated charge distribution function are computed for varying...
