WebChemical Vapor Deposition (CVD) Low-temperature chemical vapor deposition (CVD) is a process whereby a chemical precursor is vaporized and deposited onto the substrate to impart extremely dense, non-line-of-sight coatings. Typical CVD processes are high temperature (>1000°C) which limits compatibility of certain materials. WebJan 1, 2024 · Superior Abstract Molybdenum disulfide (MoS2) nanoparticles have been successfully synthesized using Chemical Vapour Deposition (CVD) technique. Inorganic precursors have been used to develop MoS2 nanoparticles. A detailed study has been carried out to investigate the influence of process parameters on morphological structure …

Fig. 6 a represents the cross section of a three-zone CVD growth chamber reported for the fabrication of monolayer MoS 2 [ 61 ].
WebCVD can be roughly divided into two types: one-step method and two-step method[13]. One-step CVD produces MoS 2 by evaporating the molybdenum source and sulfur source, this method is used in our experiment. In the two-step method, molybdenum is deposited on the substrate using a sputtering process, placed in a sulfur atmosphere, and reduced to ...
