Monolayer Behavior Retained in Bulk Semiconducting Transition Metal Dichalcogenide

Scientific Achievement

Users at the Molecular Foundry have discovered a new member of the transition metal dichalcogenides (sTMD) family, rhenium disulphide (ReS2), in which the bulk behaves as electronically and vibrationally decoupled monolayers.

Significance and Impact

Monolayer sTMDs are promising functional materials for next-generation flexible optoelectronics and photovoltaics applications but only ReS2 preserves its monolayer properties in the bulk.
