MoS2 Few-Layer Film, high purity 2D material
For applications in nanoelectronics, optoelectronics, and flexible devices
Few-layer molybdenum disulfide (MoS2), CAS number 1317-33-5, is considered to be one of the most attractive materials for next-generation nanoelectronics. This is due to its silicon-level charge mobility and high current on/off ratio in thin-film transistors. Compared to monolayer MoS2 (which needs a deposition of an additional high-k dielectric layer such as HfO2), few-layer MoS2 can be operated on its own. This makes it more appealing for fabricating transistors and other optoelectronic devices.

Applications
Molybdenum disulfide (MoS2) few-layer film, with an impressive direct band gap of 1.9 eV in the monolayer regime, has promising potential applications in nanoelectronics, optoelectronics, and flexible devices.
MoS2 few-layer films can also be made into heterostructures for energy conversation and storage devices, and used as a catalyst for hydrogen revolution reactions (HER).
Synthesis
High quality molybdenum disulfide (MoS2) few-layer films were grown directly on the substrates (SiO2/Si and Sapphire) by chemical vapour deposition (CVD) method. The films were later transferred to the desired substrates using wet chemical transfer process.
Usage
MoS2 few-layer film can be used in research purposes such as microscopic analysis, photoluminescence and Raman spectroscopy studies. Few-layer MoS2 film can also be transferred to other substrates.
