Monolayer molybdenum diselenide (1H-MoSe2) flakes have been exfoliated from bulk molybdenum diselenide (2H-MoSe2) onto 90nm thermal oxide and measures from 5micron up to 40micron in size. Each sample contains at least one single-layer MoSe2 and is easy to find with the given x and y coordinates. Full characterization is performed on each monolayer flake. Typically, single-layer MoSe2 show strong PL at 1.55eV with 0.04 to 0.07eV FWHM, and the Raman peaks are located at 287.5cm-1 (E2g in-plane mode) and 241 cm-1 (A1g out-of-plane mode). All the data is provided with the sample and data includes Raman, photoluminescence, 100x optical images, and x,y coordinates.
Characterization Raman spectroscopy: Raman spectroscopy is data is taken on every single-layer flakes. Typically, flakes show two prominent Raman peaks at 287.5cm-1 (E2g- in plane-) and 241cm-1 (A1g out-of-plane) and the FWHM (full-width-at-half-maximum) is less than 5cm-1. Photoluminescence (PL): In the single layer form, molybdenum diselenide possesses direct band-gap at 1.55eV. PL measurements show strong PL peak located at 1.56eV with 0.04-0.07 eV PL FWHM. Optical Microscope images: Each sample is inspected under the optical microscope and x-y coordinates are recorded.
