We have previously reported pyrolyzed parylene C (PPC) as a conductive carbon electrode material for use with micropipets, atomic force microscopy probes, and planar electrodes. Advantages of carbon electrode fabrication from PPC include conformal coating of high-aspect ratio micro/nanoscale features and the benefits afforded by chemical vapor deposition of carbon polymers. In this work, we demonstrate chemical surface doping of PPC through the use of previously reported methods. Chemically treated PPC films are characterized by multiple spectroscopic and electronic measurements. Pyrolyzed parylene C and doped PPC are used to construct diodes that are examined as both p-n heterojunction and Schottky barrier diodes. Half-wave rectification is achieved with PPC diodes and demonstrates the applicability of PPC as a conductive and semiconductive material in device fabrication.
我们之前曾报道过热解聚对二甲苯（PPC）作为一种导电碳电极材料，可用于微吸管、原子力显微镜探针和平面电极。由 PPC 制备碳电极的优点包括对高纵横比微/纳米结构的保形涂层以及碳聚合物化学气相沉积带来的好处。在这项工作中，我们通过之前报道的方法证明了 PPC 的化学表面掺杂。经过化学处理的 PPC 薄膜通过多种光谱和电子测量进行了表征。热解聚对二甲苯和掺杂 PPC 用于构建二极管，这些二极管被作为 p-n 异质结和肖特基势垒二极管进行了检查。PPC 二极管实现了半波整流，证明了 PPC 作为一种导电和半导体材料在器件制造中的适用性。
