论文摘要
我们将Dolan和Osheroff的开创性作品重新分析。莱特牧师。 $ \ textbf {43} $，721（1979）]，报告报告了高抗性薄膜金属条的异常低温传导。我们认为，观察到的对数的耐药性随着其3 nm厚的Au-PD条的降低而归因于不连续金属膜中对电子传导的粒度效应。我们对进行PB $ _X $（SIO $ _2 $）$ _ {1-X} $纳米胶片的测量结果进一步支持了这项重新分析，其中$ x $是Pb的音量分数。
We reanalyze the seminal work by Dolan and Osheroff [Phys. Rev. Lett. $\textbf{43}$, 721 (1979)] which reported anomalous low-temperature conduction of high-resistivity thin-film metal strips. We argue that the observed logarithmic increase of resistance with decreasing temperature in their 3-nm-thick Au-Pd strips be ascribed to the granularity effect on electron conduction in discontinuous metal films. This reanalysis is further supported by our measurements on conducting Pb$_x$(SiO$_2$)$_{1-x}$ nanogranular films, where $x$ is the volume fraction of Pb.
