ABSTRACT<\/strong><\/p>\n

After the discovery of graphene, 2D transition metal dichalcogenides (TMDs) have become a captivating group of materials. Their diverse and adjustable electronic, optical, and chemical properties have attracted significant research interest. Additionally, combining various individual TMDs in 2D material-based heterostructures offers limitless possibilities for creating new materials and exhibiting unique physical phenomena, properties, and applications. However, to meet these high expectations, it is crucial to develop scalable and cost-effective methods for producing high-quality 2D TMDs and their heterostructures. Chemical vapor deposition (CVD) is a powerful technique that has been extensively used in recent years to grow 2D materials and their heterostructures, despite some remaining challenges. In this study, we present novel CVD recipes utilizing a sodium metalate precursor \u00a0(NaMO4, M = transition metal) in conjunction with sulfur vapors at elevated temperatures to facilitate the growth of 2D TMD materials. Our findings reveal that the incorporation of sodium significantly enhances crystal growth rates, enabling the transition from a vapor-vapor reaction to a vapor-liquid-solid mechanism. This advancement has enabled the fabrication of continuous 2D TMD films encompassing monolayer and few-layer domains, with exceptional lateral dimensions exceeding 500 \u03bcm. Moreover, by adjusting precursor concentration ratios, we have successfully synthesized exceedingly large 2D TMD heterostructures both vertically and laterally. Specifically, we demonstrate the production of 2D MoS2 and WS2, along with their heterostructures, using these innovative CVD recipes. Our approach represents a significant advancement in the scalable production of large-area 2D TMDs and their heterostructures, paving the way for their integration into diverse applications in electronics, optoelectronics, and beyond. Comprehensive characterization via optical, atomic force, and scanning electron microscopies, as well as Raman and photoluminescence spectroscopies, validates the high quality and structural integrity of the synthesized materials. Additionally, we will present the response in mechanical deformation by examining the effects on specific Raman modes and excitons of TMDs. Finally, we will analyze a characteristic example of how mechanical strain impacts the performance of electronic devices, such as field-effect transistors, made from single-layer WS2.<\/p>\n
