A review on recent advances of chemical vapor deposition technique for monolayer transition metal dichalcogenides (MX2: Mo, W; S, Se, Te)

Glass‐Assisted Chemical Vapor Deposition‐Grown Monolayer MoS2: Effective Control of Size Distribution via Surface Patterning

“…The sodium ions embedded within the glass produce a highly volatile intermediate product compared with the melting point of MoO 3 precursor, reducing the growth temperature and accelerating the growth process of MoS 2 . [ 50 ] Safeer et al demonstrated experimentally and theoretically using density functional theory (DFT) that the sodium ions embedded in soda lime glass reduce the formation energy and thus the growth temperature, leading to higher growth rate, by forming a hexagonal lattice structure. [ 51 ] It was also reported that the use of glass as a catalyst eliminates the transfer process and prevents transfer‐related contamination and deterioration of flakes.…”

Electrodeposition of Hierarchical Nanosheet of NiCo2O4/CC as Highly Active and Stable Electrode for Water Oxidation

“…That is, four electrons are involved in the OER as opposed to the twoelectron process for hydrogen reduction. Furthermore, the electrocatalytic materials can be synthesized using different techniques such as physical, mechanical, and solutionbased methods [6,7]. The solution-based process in which the powder is converted to a film or deposited directly on the desired electrode substrate is attractive due to its low cost and scalability [8][9][10].…”

“…This kind of processing imposes limitations on the final film properties, including conductivity and conformality of the coating [11]. In addition, other methods such as hydrothermal processes, chemical vapour deposition (CVD), physical sputtering, and molecular beam epitaxy (MBE) are widely used to develop nanostructured materials of different shapes [6,[12][13][14][15][16][17][18][19][20][21][22][23][24]. Although the capability of these methods to produce high-quality films and diverse compositions has been proven, they suffer from pressure or vacuum requirements, temperature constraints, the need for suitable substrates, and prolonged processing time, usually in the range of 4-12 hours [6,7,11,[25][26][27][28].…”

FACILE AND CONTROLLED SYNTHESIS OF 2D ORGANOMETAL HALIDE PEROVSKITE PURE BA2MAPb2I7 AND HETEROSTRUCTURED BA2PbI4/BA2MAPb2I7 SINGLE CRYSTALS

“…Among many prominent two dimensional (2D) materials such as graphene [1] and transition metal dichalcogenides (TMD) [2][3][4], 2D organometal halide perovskites (OHPs) are promising layered materials for optoelectronic applications owing to their favorable properties such as high carrier mobility, long diffusion length, high absorption coefficient, tunable optical bandgap, and ease of forming heterostructures with other materials [5,6]. 2D OHPs structures are generally defined by the chemical formula (RNH 3 ) 2 (A) n−1 MX 3n+1 , where RNH 3 is a long-chain organic group (CH 3 (CH 2 ) 3 NH 3 , C 6 H 5 C 2 H 4 NH 3 , etc.…”
