摘要: 基于扫描探针的弯月形液滴限制电化学沉积方法(Meniscus confined electrochemical deposition,MCED)能够在微纳尺度进行结构制造和表面修饰,近年来受到了众多研究者的广泛关注。然而,在三维微纳结构制造(“写”)过程中,无法在线原位检测(“读”)加工结构形貌,导致其应用受到一定的限制。本研究对比分析了MCED微纳制造方法和扫描电化学池显微镜检测方法(Scanning electrochemical cell microscopy,SECCM)在系统物理配置和原理上的异同;提出SECCM交流调制模式对采用MCED方法制造的微纳结构进行在线原位成像,通过对比SECCM直流和交流模式的检测结果,发现交流模式能够有效克服直流模式对样本表面造成损伤的缺点,且抗干扰能力明显提高,成像图像的MSE降低了27.85%。对比扫描电子显微镜成像结果,验证了交流扫描模式能够较好的对样本进行在线原位成像,增加了MCED试验操作的在线可观测性和操作的准确性。因此,该方法使得在线MCED微纳操作可视、续接、定点修饰等功能成为可能,对扩宽MCED在微纳领域的应用具有重要意义。

Abstract: The meniscus confined electrochemical deposition method (MCED) based on scanning probes has been widely interested by many researchers in recent years, due to its ability to perform shaping and surface modification at the micro-nano scale. However, in the process of three-dimensional micro-nano fabrication, the structure morphology cannot be online "read out" in-situ, which limits its application. The study comparatively analyzed the similarities and differences in system configuration and principle between MCED and scanning electrochemical cell microscopy (SECCM). Secondly, an AC modulation mode of SECCM is proposed to in-situ image the micro-nano structure fabricated by MCED. Comparing the DC mode scanning images with AC mode, it is found that the AC scanning mode can overcome the shortcomings of the damage caused by the DC scanning mode to the surface of the sample, the anti-interference ability of the AC scanning mode is significantly improved, and the MSE of the image is decreased by nearly 27.85%. Finally, by comparing the results of AC scanning mode imaging and scanning electron microscope imaging, it is verified that AC scanning mode can better perform in-situ imaging of samples, reducing the complexity and improving the accuracy of MCED experimental operation, making online MCED micro-nano operation visualization, continuous manufacturing, fixed-point modification, etc. become possible. Therefore, this method will be of great significance for broadening the application of MCED in the micro-nano field.
