Abstract :
Charge carrier diffusion in an agglomeration of non-conducting resin grains covered with a layer of small conducting particles occurs on two scales, on single spherical grain surfaces and between different grains. Measurements of the frequency dependent permittivity between 5 Hz and 0.5 THz have been performed. The analysis allows to distinguish between the two contributions to the conductivity of the system.
