DYNAMIC TRANSPORT ON HUMID SILICA SURFACE .2.

A recent study of dynamic transport on humid silica surfaces provides data on the frequency dependence of the complex capacitance of humid s ilica rods. This is now supplemented by data on the time dependence of charging and discharging currents on humid silica rods with the relat ive humidity, rod diameter, rod length, electrode material and the app lied step voltage amplitude as the principal parameters. The results c onfirm the ''fractal'' nature of charge transport and reveal important complementary information on the non-linearity of the charging and di scharging processes.
