General Description 

Few-layer molybdenum disulfide (MoS2) 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.

High-quality molybdenum disulfide (MoS2) few-layer films are available on 2 different substrates: SiO2/Si and sapphire. Different sizes and substrates of few-layer MoSfilms are also available via custom order. Please contact us for more details.

  • Silicon (1 cm × 1 cm, 2 cm × 2 cm, 2 inch in diameter, 4 inch in diameter or custom-made sizes)
  • Quartz (1 cm × 1 cm, 2 cm × 2 cm, 2 inch in diameter, 4 inch in diameter or custom-made sizes)
  • Copper (1 cm × 1 cm, 2 cm × 2 cm, 2 inch in diameter, 4 inch in diameter or custom-made sizes)

 

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.
