Surface Conduction in a Microchannel
Langmuir, 2018Ionic current through a microchannel has drawn significant attention not only for fundamental electrokinetic research but also for the development of novel micro/nanofluidic applications. Among various ion transport mechanisms, surface conduction, which is a predominant mechanism in micro/nanofluidic devices, has been theoretically characterized based ...

Proceedings of the Institution of Electrical Engineers, 1965
This paper reviews the existing literature relating to the nature of surface conduction on solid dielectrics. Literature on the variations in conductance caused by changes in the ambient humidity, temperature and pressure; different dielectric materials and surfaces; surface contamination and the nature and magnitude of an applied voltage gradient, are

Electrochemical Impedance Imaging on Conductive Surfaces
Analytical Chemistry, 2021Electrochemical impedance spectroscopy (EIS) is a powerful tool to measure and quantify the system impedance. However, EIS only provides an average result from the entire electrode surface. Here, we demonstrated a reflection impedance microscope (RIM) that allows us to image and quantify the localized impedance on conductive surfaces.

Surface conductance of cleaved germanium surfaces
Surface Science, 1966Abstract The surface states of germanium have been investigated by measuring the change in conductance occurring upon cleavage along a (111) plane, in liquid nitrogen. Experiments were carried out with n-type samples whose donor concentrations varied from 10 13 to 10 18 /cm 3 .

Surface Conductivity of Cleaved Germanium Surfaces
Journal of Applied Physics, 1968The surface conductivity of clean germanium surfaces obtained by partial cleavage in ultrahigh vacuum has been measured for 2.0Ω·cm n-type material at room temperature by a channel technique and found to be within ±50% of 290 μmho/square. Allowing for variations in the published values of the surface hole mobility, the position of the upper edge of the

Emerging transparent conductive superhydrophobic surfaces
Advances in Colloid and Interface ScienceTransparent conductive superhydrophobic surfaces (TCSHSs) represent a novel class of multifunctional materials that concurrently exhibit high transparency, excellent electrical conductivity, and robust superhydrophobicity. These three desirable properties are synergistically combined to provide a wide variety of advantages for various optoelectronic ...

Conducting polymer surface dynamics
Journal of the Chemical Society, Chemical Communications, 1992Polymers can be used to treat fibres and films to change their wetting characteristics; poly(ethylene oxide) seems to show an orientational effect on fibres: electrical resistivity, charge decay time constant and contact angles are compared.

Origin of Surface Conductivity in Diamond
Physical Review Letters, 2000Hydrogen-terminated diamond exhibits a high surface conductivity (SC) that is commonly attributed to the direct action of hydrogen-related acceptors. We give experimental evidence that hydrogen is only a necessary requirement for SC; exposure to air is also essential.

Summary An equation for the experimental evaluation of surface conductance in plugs is described. It appears that the length over which the surface current is carried and the cross-sectional area across which the bulk current is carried are the main parameters that limit the determination of real values of surface conductance in plugs.

Electrophoresis and surface conductance
Journal of Colloid Science, 1963Abstract For microscopic particles of Pyrex glass both bare as well as covered with a layer of adsorbed bovine serum albumin, the surface conductance correction which should be applied to the electrophoretic mobility becomes important below a concentration of about 0.01 M sodium chloride.
