Abstract This paper describes the electrical characteristics of junctions of ferrocene (Fc)-containing polymer brushes (PBs) grafted on indium tin oxide (ITO) bottom electrodes contacted with eutectic gallium indium (EGaIn) top electrodes. We studied the charge transport phenomena across these junctions as a function of the PB thickness as well as the length of the tether ( i.e. , an alkyl chain side linker) between the Fc units and the polymethyl methacrylate backbone. Junctions with PBs with a thickness of 20 nm do rectify. Temperature dependent charge transport measurements revealed that the charge transport mechanism is dominated by space charge limited conduction (SCLC).

通过控制刷厚度和系绳长度来调节 ITO 上含二茂铁聚合物刷结的电荷传输

摘要 本文描述了接枝在与共晶镓铟 (EGaIn) 顶部电极接触的氧化铟锡 (ITO) 底部电极上的含二茂铁 (Fc) 聚合物刷 (PBs) 的电学特性。我们研究了作为 PB 厚度以及 Fc 单元和聚甲基丙烯酸甲酯骨架之间的连接链（即，烷基链侧链）长度的函数的跨这些连接点的电荷传输现象。具有 20 nm 厚度的 PB 的结可以进行整流。温度相关的电荷传输测量显示电荷传输机制由空间电荷限制传导 (SCLC) 主导。
