“…The proper account of the effect needs the knowledge of the spatial dispersion of the bulk dielectric permittivity ( ) ε k . Several adequate models have been proposed not only for plasma-like media (metals, doped semiconductors, electrolyte solutions) [29,37,53,[77][78][79] but also for media with bound electrons (insulators, intrinsic semiconductors) [80][81][82][83]. The quantum-mechanical character of ( ) ε k [84,85] was shown to be important in surface problems [25,27,32,33,86].…”

“…As was emphasized above, the spatial dispersion of dielectric permittivity in a semiconducting substrate influences the charge-charge interaction in the adjacent medium [22,23], although not so severely, because the screening by bound electrons is more gentle [19,25,37,[80][81][82][83]106]. The more general case of the charge-charge (ion-ion, in this case) interaction in the electrolyte solution near the metallic electrode [22,23] is also of importance, although it is more difficult to be measured directly in experiments.…”

Interaction energy between two point charges, W QQ′ , or two point dipoles, W PP′ , located in a medium with a constant dielectric permittivity near the plane surface of a metallic or semiconducting substrate with the spatial dispersion of its dielectric function has been revisited. The calculations were made on the basis of the Green's function method for layered systems. Long-range lateral asymptotics were found. The non-local character of screening in the substrates was shown to substantially modify the dependences of W QQ′ and W PP′ on the distance between the objects concerned. Thus, the purported conventional electrostatic interactions between adsorbed atoms and molecules (modeled by point charges and point dipoles) should be reconsidered making allowance for the substrate polarization. In particular, this factor may significantly influence the structure of electrostatic dipole lattices arising near the surfaces of solids, as well as the kinetics of charge or dipole motion over the surface.

Dynamical image force (polarization) energies WðzÞ induced by charged particles moving perpendicular to the vacuum-semiconductor interface or in the vacuum slab between semiconductors have been calculated on the basis of the perturbation theory developed by the authors earlier. The cases of the uniform and uniformly accelerated motions are treated as an example. The adopted dielectric approach takes into account both spatial and temporal dispersions of the electrode dielectric functions eðk; wÞ. It is shown that the quantum-mechanical character of the k-dependence of eðk; wÞ leads to a smoother WðzÞ dependence than in the semiclassical case. It is also demonstrated that the proper account of the quantum-mechanical screening behavior leads to a drastic reduction of the dynamical corrections to the static image forces. For reasonable values of the relevant parameters of the problem it is sufficient to retain only the first dynamical term of the perturbation series. Thus, the use of the expansion method is justified for multilayer semiconductor structures.
