Properties

1. In the transport properties section, the author mentioned the first FET made of bulk WSe2 has reported with a mobility below 50 cm^2 V^-1 s^-1. However, this number is not supported by a reliable reference. Meanwhile, it would be better to use transport properties from TMD monolayer instead of bulk TMDs.

2. There are many theoretical studies and experimental results to investigate the transport properties of TMDs materials. It would be better to cite these articles and provide more details to explain the transport properties of TMDs. JanusTMD (talk) 06:01, 19 March 2018 (UTC)[reply]

3. Add one section of catalytic properties in the properties section in the wikipage - Transition metal dichalcogenide monolayers Transition metal dichalcogenides exhibit a promising catalytic properties in hydrogen evolution reaction for water splitting application. The hydrogen adsorption energy of MoS2 edges is close to zero which is similar to platinum. Since 2007, MoS2 has been attracted significant attention in energy harvesting because of its highly catalytic activities.
