最近开发的基于离子轨道的 TEMPOS 类型电子结构通常填充有（半）导电纳米团簇 (NC)，以优化其操作。这里首次应用网络理论来描述离子轨迹和NC的分布，以及后者所遵循的电流路径的分布。离子径迹的存在使得NC分布偏离纯粹的随机分布。该理论用于计算给定接触周围的表面电流。可以定义此类接触周围的影响半径 (ROI)，超过该半径，表面电流可以忽略不计。 ROI 取决于磁道密度、NC 密度和电子设备的工作点。
The recently developed ion track-based electronic structures of the TEMPOS type have often been filled up with (semi)conducting nanoclusters (NCs) to optimize their operation. Network theory is applied here for the first time to describe the distribution of the ion tracks and the NC, and of the current paths followed by the latter ones. The presence of ion tracks makes the NC distribution deviate from the purely random distribution. The theory is used to calculate the electrical surface currents around a given contact. A radius of influence (ROI) around such a contact can be defined, beyond which the surface currents become negligible. ROI depends on track density, NC density and on the working point of the electronic device.
