Description
Monolayer tungsten disulfide (1H-WS₂) flakes have been exfoliated from bulk tungsten disulfide (2H-WS₂) onto 90nm thermal oxide and measures from 5micron up to 40micron in size. Each sample contains at least one single-layer WS₂ and is easy to find with the given x and y coordinates. Full characterization is performed on each monolayer flake. Typically, single-layer WS₂ show strong PL at 2.02eV with 0.04 to 0.08eV FWHM, All the data is provided with the sample and data includes Raman, photoluminescence, 100x optical images, and x,y coordinates.Photoluminescence (PL): In the single layer form, tungsten diselenide possesses direct band-gap at 2.02eV. PL measurements show strong PL peak located at 2.02V with 0.04-0.08 eV PL FWHM.Optical Microscope images: Each sample is inspected under the optical microscope and x-y coordinates are recorded.
