The dominating transport mechanism is a metallic-like conductivity of charges partly confined in constituting nano-grains. The scattering time at low temperatures is limited by scattering by ionized defects and the conductivity is strongly suppressed due to capture of a major fraction of charge carriers in deep traps.
