我们已经设计了一个电沉积系统，采用多个旋转圆盘电极（RDE）在一个单一的电化学浴，目的是开发一种手段，以获得均匀的氧化锌（ZnO）薄膜具有高的重现性，因为该反应是已知的强烈限制质量传输。采用导电和绝缘带，将背侧不具有导电性的诸如F掺杂的SnO2（FTO）涂覆的玻璃的基板设置成RDE的几何形状。通过试验确定了活性电极区域的形状。此外，测试了RDE在电化学浴中的位置的影响。在确认相邻的RDE不会相互干扰之后，将八个RDE像轮盘一样放置在单个电解槽中。使用8个RDE系统电沉积得到的8个ZnO样品几乎相同，其厚度的标准偏差小于0.3%。(C)日本电化学学会，版权所有。
We have designed an electrodeposition system employing multiple rotating disc electrodes (RDE) in a single electrochemical bath, with an aim to develop a mean to obtain homogeneous zinc oxide (ZnO) thin films with a high reproducibility, as the reaction is known to be strongly limited by mass transport. Substrates such as F-doped SnO2 (FTO) coated glass having no electric conduction on the back side were furnished into a geometry of RDEs employing conductive and insulating tapes. The shape of the active electrode area was determined through tests. Also, the influence of the position of the RDE in the electrochemical bath was tested. Having confirmed that neighboring RDEs do not interfere each other, eight RDEs were placed like a roulette in a single electrolytic bath. The resulting eight ZnO samples electrodeposited by using the eight RDE system were almost identical with the standard deviation of less than 0.3% for their thickness.
