CVD method monolayer WS2 is a promising member of the 2-D graphene-like materials series at ACS Material. WS2 is a member of the transition metal dichalcogenide group and is also commonly known as tungsten sulfide and tungsten (IV) sulfide. Among 2-D materials with tailored morphologies designed to enhance their performance in nanoelectronics, WS2 stands out as a particularly promising candidate.
WS2 monolayer films demonstrate superior optical properties, indicated by exceptional line widths and photoluminescent quantum yield. In addition, WS2 monolayer films exhibit large spin-orbit coupling and larger valence band splitting, leading many researchers to believe that WS2 monolayer films may exhibit exceptional band-edge spin splittings, a strong valley Hall effect, and the magnetic field effects necessary for optoelectronic and spintronic functionalities.
High-quality tungsten disulfide monolayer film from ACS Material is available as a CVD-grown film on sapphire, Al2O3, or SiO2 substrates. Potential applications include transistors, sensors, and other electronic and photovoltaic devices; whatever your purposes, you’ll be impressed with the performance and consistent quality of CVD method monolayer WS2 provided by ACS Material.
