In the presence of weak disorder, one should consider an additional contribution to the resistivity due to weak localisation resulting from quantum interference effects and/or that due to Coulomb interaction effects. A single-carrier weak localisation effect is produced by constructive quantum interference between elastically back-scattered partial-carrier-waves, while disorder attenuates the screening between charge carriers, thus increasing their Coulomb interaction. So, both effects are enhanced in the presence of weak disorder, or, in other words, by defect scattering. This was previously discussed for the case of carbons and graphites [7]. 

If the defects can be considered point charges, localized on their own lattice sites, the polar electrostatic interaction between them is usually written as a long range monopolar Coulomb energy. If, on the other hand, for large concentrations of defects, local charge effects, as described in the introduction, are present, then AHjnter is much more difficult to write. 

Origin Preferential evaporation of the lighter isotope from the sample filament Preferential radial deflection of lighter ions from the center of ion beam (Coulomb repulsion due to space charge effects of charged ions - loss in ion transmission)... 

FIGURE 3.11 For large separations, the complicated interaction between the 37 charged particles in K+ and the 35 charged particles in Cl- reduces to simple Coulombic attraction between the two net charges. Effects from the spherical electronic clouds and the small nucleus tend to cancel (see Figure 3.2). 

This necessary condition corresponds to the onset of shuttling and has been found in Ref. [Fedorets 2002], For ttCl, however, Eq. 30 can be utilized only at the beginning of the instability, because in this approximation the charge is independent of Uc, which does not account for the Coulomb blockade effect.
