Abstract: | It is predicted that at room temperatures a hopping mechanism of charge transfer plays a very important role and leads to
temperature oscillations of the conductivity σ(T) of a dielectric composite. The dependence of the conductivity σ(ω) on the frequency of an alternating electric field is calculated. The relation obtained can be used to determine, first,
the electron relaxation times and, second, and more importantly, the frequency of electron tunneling through the dielectric
matrix from measurements of the conductivity in various frequency ranges.
