Here, we propose a salt-assisted chemical vapor deposition with pre-spin-coating precursors to advance the fabrication of MoSe<sub>2</sub>/graphene heterojunctions, in which Se vapor and H<sub>2</sub> gas are transported to react with the molten Na<sub>2</sub>MoO<sub>4</sub> and NH<sub>4</sub>Cl salts atop the graphene layer for the MoSe<sub>2</sub> growth. The effects of H<sub>2</sub> flowrate, temperature and time of reaction, composition and ratio of elements in the salt precursors, as well as the layer number of graphene film, are investigated. The results demonstrate that a liquid eutectic salt complex, consisting of sodium-molybdenum-oxyhalide, is an essential transient intermediate, and the growth follows a novel vapor–liquid/vapor–solid (V–L/V–S) mechanism. By optimizing the growth parameters, MoSe<sub>2</sub>/graphene heterojunctions with the monolayer up to 80 % of MoSe<sub>2</sub> are synthesized with the lattice alignment of graphene (100) to MoSe<sub>2</sub> (100). The interaction between graphene and MoSe<sub>2</sub> is monitored by the Raman, UV–Vis and PL spectra. Additionally, carrier inversion phenomenon in MoSe<sub>2</sub>/graphene heterojunction is found relying on the light illumination intensity. These results contribute new insights into the controllable synthesis and fascinating properties of graphene-based TMDs heterojunctions.</div></div>","PeriodicalId":262,"journal":{"name":"Carbon","volume":"240 ","pages":"Article 120377"},"PeriodicalIF":10.5,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143891792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This investigation delves into the nanoscale interface friction and mechanical behavior between DLC and polycrystalline austenitic stainless steel. Molecular dynamics simulations were employed to model the sliding interface structure's evolution and friction performance under differing contact pressures and graphitization states. In the friction sliding process, carbon atoms predominantly experience surface structural reorganization with minimal diffusion. The displacement of stainless steel's internal atoms is chiefly driven by deformation rather than diffusion. The study also examines the synergistic impacts of external pressure, structural transformations, and interfacial compounds on the system's friction mechanism. At low contact pressures (≤8 GPa), austenite deformation and recrystallization triggered by friction were noted. Conversely, at high junction pressures (>8 GPa), the interplay of stress and strain induces martensitic transformation in stainless steel and amplifies mechanical mixing with DLC. The α′-martensite proportion correlates positively with contact pressure and friction duration. An uptick in martensite content escalates the system's friction force; however, when the system's friction is governed entirely by martensite, it manifests a stable low friction force. Furthermore, under varied carbon atom hybridization conditions, systems characterized by high sp<sup>3</sup> hybridization display increased strain and friction. These insights provide valuable perspectives for improving the research on DLC and stainless steel nano micro interfaces.</div></div>","PeriodicalId":262,"journal":{"name":"Carbon","volume":"240 ","pages":"Article 120371"},"PeriodicalIF":10.5,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143886211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
