Suspended Monolayer MoS2, WS2, MoSe2, and WSe2 Flakes



1.  Single crystalline monolayer flakes transferred onto substrates with pre-defined holes. The holes are in diameter of  ranging from 2 to 30 micrometers.  Other size is available upon request.

2. The materials may be monolayers of MoS2, WS2, MoSe2, and WSe2. Customers are expected to explicitly specify the materials when placing orders.

3. The depth of the holes is in the range of 20-30 micrometers.  Option of through holes is available upon request.

4.Complete elimination of the effect of substrates.  PL efficiency of the suspended monolayers is one or two order magnitude higher than that of as-grown counterparts.

5. Typical substrates are SiO2/Si (280 nm thick oxide) with pre-defined holes.  Other substrates such as quartz and sapphire are available upon request.

Product Description

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.
