surface resistivity

[′sər·fəs ‚rē‚zis′tiv·əd·ē]
(electricity)
The electric resistance of the surface of an insulator, measured between the opposite sides of a square on the surface; the value in ohms is independent of the size of the square and the thickness of the surface film.

Offered in black only, their surface resistivity is less than 105 Ohms per square.
It has been perceived since long that the integration of resistivity parameters extracted from surface resistivity measurement has a strong correlation between aquifer properties, as electrical properties are affected by porosity, permeability, heterogeneity, orientation of grains, compaction and consolidation (Mazac et al., 1985; Huntley, 1986; Mazac et al., 1988; Borner et al., 1996; Christensen and Sorensen, 1998; de Lima et al., 2005; Niwas et al., 2006; Rubin and Hubbard, 2006).
Moreover, also in our previous article on PLA based nanocomposites it was reported how the combination of vapor grown carbon fibers (VGCF) and exfoliated graphite nanoplatelets (xGnP) fillers promoted a further decrease of surface resistivity with respect to the corresponding binary systems [28].
The measurements are taken by several available methods based on uniaxial or bulk resistivity, surface resistivity, electrical impedance spectroscopy, and noncontact resistivity measurements based on the transformer principle [1-5].
The modification with heavy atoms might lead to more sensitive graphene sensors as due to increased surface resistivity large current spikes might be easier to detect.
Designed for use with the vendor's Model 6517B electrometer and Model 8009 resistivity chamber, the KICKSTARTFL-HRMA application automates volume and surface resistivity measurements for accurate and repeatable results without the need for custom programming.
Previously, we have reported measurements of the temperature-dependent surface resistivity of pure and multi-walled carbon nanotubes doped amorphous Polyvinyl Alcohol (PVA) thin films.
Also, different approaches in the measurement of concrete resistivity including bulk and surface resistivity measurements are presented.
The surface resistivity of the sample layer is increased with the increase of injection pressure, and the resistivity of subsurface and core decreases with the increase of injection pressure.
