| Abstract: | It is shown that the thermodynamically equilibrium state of a system of small metal particles placed in a dielectric matrix
are unavoidably charged. The charge of spherical metal particles with different radii is calculated at low temperatures. Hopping
transport in a system of metal particles is studied. It is shown that it is limited by the charging energy, which serves as
a typical hopping energy and can be gapless.
