Temperature-dependent conductivity of Pt–C FEBID structures that have been exposed to different post-growth electron irradiation doses as indicated. (a) As-grown briefly irradiated samples show thermally activated behavior following the correlated VRH scenario. (b) Long-term irradiated samples reveal a logarithmic temperature dependence of the conductivity in accordance with Equation 27. Saturation of this behavior is observed below about 15 K. (c) Samples in the metallic regime at low temperature show indications for a crossover to a -dependence of the conductivity. The straight dashed orange lines in the plots are meant to facilitate a judgement of the quality of the temperature dependence of the conductivity as predicted by theory. See text for details.
