Data underlying the publication: A Ferritin Single-Electron Transistor

This data set corresponds to the data underlying the article "A Ferritin Single-Electron Transistor". In this study, we report, for the first time, on single-electron transistors with ferritin particles, characterized at low temperatures. Our approach is based on wide (micron scale) and small (8-25 nm) self-aligned-nano-gaps devices that facilitate the trapping of single ferritin particles. Underneath the gap area a local back gate is placed, which allows the study of the transport properties as a function of gate voltage. The data is in excellent agreement with the Coulomb blockade model, revealing single-electron tunneling as the transport mechanism through them. Additionally, the three-terminal electrical measurements suggest the presence of two separate islands coupled in series or in parallel; information that was not possible to distinguish by using only two-terminal measurements. <br>All data displayed in the Manuscript and in the Supporting Information are stored in the file "raw data.zip", as raw data. The zip file contains two different folders: 1) mainArticle: it contains the raw data used in the manuscript. 2) SI: it has the raw data displayed in the Supporting Information. Each subfolder contains separate ReadMe files. In each of them, the format and different considerations for displaying the data are described.<br>

本数据集对应论文"A Ferritin Single-Electron Transistor"（铁蛋白单电子晶体管）所依托的实验原始数据。本研究首次报道了搭载铁蛋白颗粒的单电子晶体管（single-electron transistor），并在低温环境下完成了其电学特性表征。本研究采用宽尺度（微米级）与窄间隙（8~25 nm）的自对准纳米间隙（self-aligned-nano-gaps）器件，可高效捕获单个铁蛋白颗粒。间隙区域下方设置有局部背栅（local back gate），能够实现输运特性随栅极电压变化规律的调控与研究。实验数据与库仑阻塞模型（Coulomb blockade model）吻合度极佳，证实单电子隧穿（single-electron tunneling）为该器件的主导输运机制。此外，三端电学测量结果显示存在两个以串联或并联方式耦合的独立岛结构，此类信息仅通过二端测量无法实现区分。
论文正文与补充材料中展示的全部原始数据均存储于"raw data.zip"压缩包内。该压缩包包含两个子文件夹：1）mainArticle：存储论文正文所用的原始数据；2）SI：存储补充材料中展示的原始数据。每个子文件夹均配有独立的ReadMe文件，其中详细说明了数据的格式规范与相关注意事项。
