英文摘要	Oxygen is one of the most abundant elements on earth, and even small amounts of oxygen can induce significant changes in material properties. In this study, we combined a non-oxide semiconductor molybdenum disulphide (MoS2) with an oxide semiconductor zinc oxide (ZnO), thereby simultaneously obtaining oxygen vacancies and oxygen incorporations through a novel oxidation-assisted strategy. This strategy amplified interactions between semiconductor substrates and probe molecules and increased charge-transfer resonance, thereby substantially improving the surface-enhanced Raman spectroscopy (SERS) performance of semiconductor materials. The enhancement factor of MoS2@ZnO was increased to a value comparable to that of traditional metals, enabling it to detect methylene blue with a limit of detection as low as 1012 M. Additionally, a comparison sample (MoS2@ZnS) was examined to confirm the unique enhancement effect of the proposed strategy for SERS. The effect of the proposed oxygen bidirectional strategy on the SERS performance of semiconductor substrates can provide new frontiers in the development of ultrasensitive semiconductor technologies. 2020 Elsevier B.V.
