MoS2 Monolayer Film, for applications in electronic and optoelectronic devices

High quality and available online for fast, secure dispatch

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.

Applications of Molybdenum Disulfide Monolayer Film


Applications in electronic and optoelectronic devices


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


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.


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.
