In this study, we applied coaxial arc plasma deposition in vacuum and without substrate heating to prepare composite films of boron‐doped nanocrystalline diamond and amorphous carbon (B‐doped NCD/a‐C) exhibiting electrochemical characteristics similar to those exhibited by the conductive polycrystalline diamond electrodes. Furthermore, we confirmed that the deposited films can be used to determine the current density owing to various concentrations of potassium ferricyanide (K₃[Fe(CN₆)]). Moreover, the concentration of K₃[Fe(CN₆)] and its current density were strongly correlated. Based on these experimental results, the deposited films were highly valuable as electrodes for electrochemical sensors. © 2020 Institute of Electrical Engineers of Japan.

同轴电弧等离子体沉积法制备的硼掺杂纳米晶金刚石与非晶碳复合膜的电化学检测特性

在这项研究中，我们在真空中且没有衬底加热的情况下应用同轴电弧等离子体沉积来制备硼掺杂的纳米晶金刚石和非晶碳（B掺杂的NCD / a-C）的复合膜，该复合膜的电化学特性与导电多晶相似金刚石电极。此外，我们证实，由于铁氰化钾（K ₃ [Fe（CN ₆）]）的浓度不同，所沉积的膜可用于确定电流密度。此外，K ₃ [Fe（CN ₆）]及其电流密度密切相关。基于这些实验结果，沉积的膜作为电化学传感器的电极非常有价值。©2020日本电气工程师学会。由John Wiley＆Sons，Inc.发布
