| Abstract: | Monolayer Mo1 xWxSe2 (x¼0, 0.14, 0.75, and 1) alloys were experimentally realized from synthesized crystals. Mo1 xWxSe2 monolayers are direct bandgap semiconductors displaying high luminescence and are stable in ambient. The bandgap values can be tuned by varying the W composition. Interestingly, the bandgap values do not scale linearly with composition. Such non-linearity is attributed to localization of conduction band minimum states around Mo d orbitals, whereas the valence band maximum states are uniformly distributed among W and Mo d orbitals. Results introduce monolayer Mo1 xWxSe2 alloys with different gap values, and open a venue for broadening the materials library and applications of two-dimensional semiconductors. |
