“…One of the common and commercially attractive methods of two-dimensional materials synthesis is a method of chemical vapor deposition (CVD). Recent studies have shown the principal possibility for this method use for synthesis of both 2D/2D and 2D/3D heterostructures [15,16]. Conventionally used CVD chamber is a heated quartz tube with precursors and substrate inside [17].…”

In this work thin film coatings based on WS2, MoS2, MoO2 and their composites were synthesized, morphological and structural properties of deposited coatings were studied. Chemical vapor deposition with heated MoO3, WO3, S powder as precursors was used. Dependence of structural and morphological properties, chemical composition of deposited films on parameters of synthesis was defined. Films of vertically aligned 10 nm thick plate crystals consisting both of pure MoO2 and MoO2 covered with thin MoS2 layer were obtained. Formation of polycrystalline films of regular triangular shaped WS2 and uniform continuous 20 nm thick WS2 films with covering area of 2x2 mm has also been observed. In this work we also report about synthesis of films consisting of regular triangular shaped WS2 crystals and MoS2 irregularly shaped crystals overlapping each other. Keywords: 2D materials, transition metal dichalcogenides, heterostructures, CVD, AFM.

“…Одним из самых распространенных и коммерчески привлекательных методов синтеза двумерных материалов является метод химического газофазного осаждения (chemical vapor deposition -CVD). Недавние исследования показали принципиальную возможность использования этой методики для синтеза как 2D/2D-, так и 2D/3D-гетероструктур [15,16]. Стандартно используемые CVD-камеры представляют собой нагреваемую кварцевую трубу с расположенными внутри прекурсорами и подложкой [17].…”

“…Designing mixed-dimensional heterostructures − by interfacing two-dimensional (2D) graphene oxide (GO) layers with one-dimensional (1D) zinc oxide (ZnO) nanorods is paramount to the understanding of existing dipolar van der Waals interactions and interfacial charge carrier transport. Interfacing GO with ZnO nanorods creates mixed-dimensional 2D/1D heterostructures with potential applications in biosensors, − UV detectors, , dye-sensitized solar cells, − perovskite tandem cells, − and catalysis. , Conventionally, GO/ZnO nanocomposites are fabricated by either chemical vapor deposition, , spray pyrolysis, , spin-coating methods, and/or via the traditional drop-casting technique , of GO on a hydrothermally grown ZnO substrate.…”

Interfacing two-dimensional graphene oxide (GO) platelets with one-dimensional zinc oxide nanorods (ZnO) would create mixed-dimensional heterostructures suitable for modern optoelectronic devices. However, there remains a lack in understanding of interfacial chemistry and wettability in GO-coated ZnO nanorods heterostructures. Here, we propose a hydroxyl-based dissociation-exchange mechanism to understand interfacial interactions responsible for GO adsorption onto ZnO nanorods hydrophobic substrates. The proposed mechanism initiated from mixing GO suspensions with various organics would allow us to overcome the poor wettability (θ ∼ 140.5°) of the superhydrophobic ZnO nanorods to the drop-casted GO. The addition of different classes of organics into the relatively high pH GO suspension with a volumetric ratio of 1:3 (organic-to-GO) is believed to introduce free radicals (−OH and −COOH), which consequently result in enhancing adhesion (chemisorption) between ZnO nanorods and GO platelets. The wettability study shows as high as 75% reduction in the contact angle (θ = 35.5°) when the GO suspension is mixed with alcohols (e.g., ethanol) prior to interfacing with ZnO nanorods. The interfacial chemistry developed here brings forth a scalable tool for designing graphene-coated ZnO heterojunctions for photovoltaics, photocatalysis, biosensors, and UV detectors.
