Shklovskii B. I. Variable range hopping in thin film with large dielectric constant [Електронний ресурс] / B. I. Shklovskii // Физика низких температур. - 2017. - Т. 43, № 6. - С. 879-883. - Режим доступу: http://nbuv.gov.ua/UJRN/PhNT_2017_43_6_11 In a film with large dielectric constant - the electric field of an electron spreads inside the film before exiting the film at large distances of order of <$E kappa d> (d is the film width). This leads to the logarithmic Coulomb repulsion between electrons and modifies the shape of the Coulomb gap in the density of localized states in a doped film. As a result the variable range hopping conductivity in such a film has a peculiar temperature dependence, where the domain of the <$E ln sigma (T)~symbol Х~(T sub 0 "/" T) sup p> dependence, with the index <$E p~symbol Ы~0,7>, is sandwiched between the two domains with p = 1/2.
