General Description 

Molybdenum disulfide (MoS2) monolayer film is a direct bandgap semiconductor. When in bulk form however, this material has an indirect bandgap. The photoluminescence of MoSfilms increases with decreasing layer thickness. This means that luminescence is strongest in monolayer films, while it is absent in bulk material.

High-quality molybdenum disulfide monolayer films are available on 2 different substrates: SiO2/Si and Sapphire. Different sizes and substrates of monolayer MoSfilms are also available via custom order. Discontinuous isolated triangular crystals (crystal islands) films are also available via custom request,  please contact us for more details.

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

Applications

Molybdenum disulfide monolayer films can be built into electronic and optoelectronic devices such as photovoltaic solar cells, FETs, sensors, and photodetectors.

Synthesis 

High-quality molybdenum disulfide monolayer films were grown directly on the substrates (SiO2/Si and Sapphire) by the chemical vapour deposition (CVD) method. The films were later transferred to the desired substrates using wet chemical transfer process.

Usage

MoS2 monolayer film can be used in research purposes such as microscopic analysis, photoluminescence, and Raman spectroscopy studies. MoS2 few-layer film can also be transferred to other substrates.
