Electrical Conductivity of Films with Negative Dielectric Permittivity

Phenomena in Polarized Disperse Systems Caused by Exchange-Correlation Interaction between Particles

“…For this reason, the condition ε < 0 is experimentally satisfied for dielectric powders containing the donor centers only on the particle surfaces. For powders with a bulk doping of their particles, the inequality ε < 0 does not hold [8].…”

“…is the static dielectric permittivity [8] [9]. For example, this condition has been used to explain the zero ohmic loss for a direct current in Al 2 O 3 and NiO powders containing donor centers on the nanoparticle surfaces in the form of interstitial hydrogen atoms [8].…”

The zero ohmic loss has also been observed for a sine-wave current in finely dispersed compounds KMnO 4 [8] [10] and KNaC 4 H 4 O 6 •4Н 2 О [9] placed in molecular hydrogen and vacuum, respectively.…”

In the case of the finely dispersed dielectrics KMnO 4 , Pb(NO 3 ) 2 and CsNO 3 with donor centers on the particle surfaces, there is observed spontaneous emergence of a macroscopic electric field [11] [12] [13].…”

“…The aim of the present work is to carry out a theoretical study of conditions under which the static dielectric permittivity of the systems consisting of semiconductor and dielectric nano-and microparticles becomes negative. Besides, we have solved the problem of a theoretical description of the properties of such systems observed in the experiments [8]- [13].…”
