ReS2 (Rhenium Disulfide)
ReS2 is a direct-bandgap semiconductor of ~1.35 eV. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. Rhenium Disulfide belongs to the group-VII transition metal dichalcogenides (TMDC).

The ReS2 crystals produced at HQ Graphene typically look similar to a flower with a lateral size of ~-0.8 cm, where multiple single crystals resemble the petals and the appearance is dark metallic.
We produce n-type ReS2, having a typical charge carrier density of ~1017cm-3 at room temperature.
