摘要

提出了一种自端电化学原子层沉积工艺，逐层制备金单层膜。发现在每次ML沉积后，下电位沉积的氢(Hupd)提供了完美的终止，并且在使用正电位去除Hupd层的表面活化后，可以复制进一步的ML生长。伏安测量、沉积电流分析和EQCM显示了UPD氢表面终止和ML沉积的明显特征。XRR和HREED都证实了Au ML膜的形成。此外，Au - ML膜似乎对氧化石墨烯在Au - ML膜上的表面增强拉曼效应有效。

Au monolayer film coating with graphene oxide for surface enhanced Raman effect

A self-terminated electrochemical atomic layer deposition process is developed to fabricate Au monolayer (ML) film layer-by-layer. It is found that the under potential deposited hydrogen (H_upd) provides perfect termination after each ML deposition and the further ML growth can be replicated after a surface activation using a positive potential to remove the H_upd layer. Voltammetric measurements, deposition current analysis, and EQCM show clear characteristics of UPD hydrogen surface termination and the ML deposition. Both XRR and HREED confirm the Au ML film formation. Moreover, the Au ML film appears to be effective for surface enhanced Raman effect of GO on the Au ML film.
