| Monolayer WS2 on 2" sapphire | Monolayer WS2 is a semiconducting transition metal dichalcogenide (TMD) with a direct bandgap in the monolayer. Wafer-scale epitaxial growth of monolayer WS2 on 2-inch sapphire substrates enables highly uniform films suitable for scalable electronic and optoelectronic applications. | 2-inch wafer | Monolayer | Direct growth on 2" Sapphire | AFM, Raman, PL |
Characterization at center of 2" wafer: AFM: Fully coalesced monolayer (>95% monolayer) and <15% bilayer coverage. Raman Spectroscopy: The FWHM of the E2g/2LA(M) feature near 356 cm-1 of < 6 cm-1 PL Spectroscopy: The PL peak position is varified to be in the range of 1.95â2.02 eV. |
