2014年11月4日 · Atmospheric-pressure chemical vapor deposition (CVD) is used to grow monolayer MoS 2 two-dimensional crystals at elevated temperatures on silicon substrates with a 300 nm oxide layer.

2023年3月15日 · Control over thickness, size, and area of chem. vapor deposition (CVD) grown molybdenum disulfide (MoS2) flakes is crucial for device application. Herein, we report a quant. comparison of CVD synthesis of MoS2 on SiO2/Si substrate using three different precursors viz., molybdenum trioxide (MoO3), ammonium heptamolybdate (AHM), and tellurium (Te).

2017年5月8日 · In this work, we reveal the growth kinetics of 2D MoS 2 by capturing the nucleation seeds, evolving morphology, edge structure, and edge terminations at the atomic scale during chemical vapor...

2024年1月17日 · Here, we propose a reconfiguring nucleation chemical vapor deposition (CVD) strategy for directly synthesizing TB-MoS 2 with twist angles from 0° to 120°. The twist angles-dependent Moiré...

2017年12月22日 · In this work, we present a systematic spectroscopic study of CVD-grown MoS 2, and two types of MoS 2 flakes have been identified: one type of flake contains a central nanoparticle with the multilayer MoS 2 structure, and the other is dominated by triangular flakes with monolayer or bilayer structures.

2018年4月27日 · Here, we study the bioabsorption of CVD-grown monolayer MoS 2, including long-term cytotoxicity and immunological biocompatibility evaluations in biofluids and tissues of live animal models....

Molybdenum disulfide (MoS2) synthesized via chemical vapor deposition (CVD) is commonly accompanied by some intermediate products in the form of MoO3−x, resulting in MoS2–MoO3−x hybrids with diverse structures. In this study, we show that through the rational design of heating evaporation rate of the precurs Crystal Growth

2024年7月1日 · In this work, we demonstrate the growth of large-area continuous films of MoS 2 using solution-cast MoS 2 seed nanoflakes, both with and without the assistance of alkali halide. The MoS 2 seed nanoflakes serve as nucleation sites for the in-plane growth of few-layer MoS 2, which is accompanied by localized vertical growth of MoS 2 particles.

2024年12月27日 · Two-dimensional (2D) films of MoS2 (MoS2-2D) were deposited on low-resistivity SiO2/Si substrates via the chemical vapor deposition (CVD) technique and subjected to p-doping with oxygen by annealing at different temperatures.

2023年1月1日 · In this work, we designed a gradient of sulfur (S) concentration during CVD growth of MoS 2 to investigate how S concentration affects its size and shape change. The shape of MoS 2 film changes from triangle to hexagon, then …
