Large-Scale Ultra-Robust MoS2 Patterns Directly Synthesized on Polymer Substrate for Flexible Sensing Electronics

Weiwei Li et al.

Summary: A method combining inkjet printing and thermal annealing is reported to directly synthesize large-scale MoS2 patterns. The patterned MoS2 is obtained directly on a polymer substrate through thermal treatment in an atmosphere of argon/hydrogen. This approach is used to manufacture various flexible sensing devices that are insensitive to body motions and moisture.

Salt-Assisted MoS2 Growth: Molecular Mechanisms from the First Principles

Jincheng Lei et al.

Summary: Recently, it has been found that halide salts can promote the chemical vapor deposition (CVD) growth of two-dimensional transition metal dichalcogenides (TMD). In this study, the molecular mechanisms during the salt-assisted CVD growth of MoS2 monolayers were investigated using first-principles calculations and ab initio molecular dynamics (AIMD) simulations. The sulfurization of molybdenum oxyhalides was explored and found to have much lower activation barriers than molybdenum oxide, which is present during conventional saltless growth. The rate-limiting barriers were found to depend linearly on the electronegativity of the halogen element, with oxyiodide having the lowest barrier. This study reveals the promoting mechanisms of halides and allows growth parameter optimization for faster growth of MoS2 monolayers in CVD synthesis.

NaCl-Assisted Temperature-Dependent Controllable Growth of Large-Area MoS2 Crystals Using Confined-Space CVD

Muhammad Suleman et al.

Summary: This paper reports the large-scale growth of MoS2 with different morphologies using NaCl as a seeding promoter for confined-space CVD. Changes in the morphologies of MoS2 are achieved by varying the amount of seeding promoter, precursor ratio, and growth temperature. The electrical properties of the grown MoS2 show promising performance for field-effect transistors. This work provides new insight into the growth of large-area MoS2 and opens up possibilities for its optoelectronic and electronic applications.

Aditya Singh et al.

Summary: A facile NaCl-assisted Chemical Vapor Deposition (CVD) method was used to synthesize high-quality MoS2 on different substrates, with sapphire and SiO2/Si suitable for large flakes growth and mica suitable for continuous films. 1L-MoS2 on sapphire exhibited high crystalline quality, while on other substrates like quartz and bare Si, the quality was poorer. The study highlights the role of NaCl in promoting the formation of seeding promoter and facilitating layer transfer for large-scale synthesis of high-performance optoelectronic devices.
