研究了含钴纳米颗粒的无定形碳在总钴浓度低于渗透阈值时电导率的温度依赖性。建立了该结构中的电子输运是由非弹性共振电子隧穿局域态决定的，局域态位于绝缘导电金属团簇之间的介电碳基体中。定域态的数目是作为复合材料中钴浓度的函数来确定的。
The temperature dependence of electric conductivity was studied in a granular amorphous carbon containing cobalt nanoparticles at an overall cobalt concentration below the percolation threshold. It was established that the electron transport in this structure is determined by the inelastic resonance electron tunneling via localized states, which are situated in the dielectric carbon matrix between isolated conducting metal clusters. The number of the localized states is determined as a function of the cobalt concentration in the composite.
