研究了热解多孔酚醛树脂蛋白石复制品的电导率和磁导率随热处理温度(HTT)高达2380℃的变化规律。在具有低HTT的复制品的情况下，实验观察到在降低温度后从Mott可变范围跳跃(VRH)到EFros和Shklovskii VRH的交叉。对于高HTT的，其电学性能与热解石墨的电学性能一致。正磁导的出现表明低温下量子效应的存在。
The electrical conductivity and magnetoconductance of pyrolized porous phenolic resin opal replicas have been studied as a function of their heat treatment temperature (HTT) up to 2380°C. Porous graphite can be formed by pyrolizing the phenolic resin opal replica. In the case of replicas with a low HTT, a crossover from Mott variable range hopping (VRH) to Efros and Shklovskii VRH upon decreasing the temperature has been experimentally observed. For those with a high HTT, the electrical properties are consistent with those of pyrolytic graphite. The occurrence of positive magnetoconductance indicates the existence of quantum effect at low temperatures.
