Suspended 2D transition metal dichalcogenide (TMDC) flakes may completely eliminate the effect of substrates and provide mechanical flexibility. These materials are particularly suited for studying intrinsic electronic and optical properties, developing high-performance optical or electronic devices, and being used as mechanical resonators.
The suspended flakes are made by transferring CVD-grown single crystalline flakes onto substrates with pre-patterned holes. The crystalline and surface quality of the films can be nicely preserved with no residual and contaminants left during the transfer process.
2Dlayer may supply suspended monolayer flakes of MoS2, WS2, MoSe2, and WSe2.
Compared to typical 2D TMDC materials that are supported by substrates, suspended 2D TMDC materials essentially eliminate the effects of substrates and thus provide opportunity to study the intrinsic properties of the materials. For instance, by eliminating the adverse effect of the substrate, the PL efficiency of monolayer TMDC can be improved by more than two orders of magnitude.
