[en] The production of the vertically aligned MoS₂ nanosheets has been generating an enormous interest due to their potential applications in the diverse research fields. However, the production methods for such vertical nanosheets, especially via chemical vapor deposition (CVD) route, used so far have involved complex- or multi-growth processing steps. To meet this demanding challenge, in this work we report high quality vertically aligned MoS₂ nanosheets grown by CVD in a single growth step, with reduced complexity of the growth processing steps. For the first time, we also studied the effect of substrate angle (ranging from 0° to 90°) during the growth on surface morphology, structural, and Raman spectroscopy properties of the as-grown MoS₂ vertical nanosheets. The results demonstrated that high quality vertically aligned nanosheets with packed density can possibly be achieved at 90° substrate angle. The characterizations such as XRD, HR-TEM and SAED patterns confirm the vertical orientation while SEM images reveal the excellent surface morphology and packed density of the MoS₂ vertical nanosheets. Additionally, Raman spectroscopy studies further evident of the verticality nature of the high quality nanosheets while XPS data confirmed that the as-grown material is of MoS₂. The relevance of the work is discussed in the context of the present fabrication methods for such vertically aligned MoS₂ nanosheets and also suggested their domains of applications. (paper)
