Due to its semiconducting nature, controlled growth of
large-area
chemical vapor deposition (CVD)-grown two-dimensional (2D) molybdenum
disulfide (MoS
2
) has a lot of potential applications in
photodetectors, sensors, and optoelectronics. Yet the controllable,
large-area, and cost-effective growth of highly crystalline MoS
2
remains a challenge. Confined-space CVD is a very promising
method for the growth of highly crystalline MoS
2
in a controlled
manner. Herein, we report the large-scale growth of MoS
2
with different morphologies using NaCl as a seeding promoter for
confined-space CVD. Changes in the morphologies of MoS
2
are reported by variation in the amount of seeding promoter, precursor
ratio, and the growth temperature. Furthermore, the properties of
the grown MoS
2
are analyzed using optical microscopy, scanning
electron microscopy (SEM), Raman spectroscopy, X-ray photoelectron
spectroscopy (XPS), energy-dispersive X-ray spectroscopy (EDX), and
atomic force microscopy (AFM). The electrical properties of the CVD-grown
MoS
2
show promising performance from fabricated field-effect
transistors. This work provides new insight into the growth of large-area
MoS
2
and opens the way for its various optoelectronic and
electronic applications.
