Description
MoS2 (2H phase) is a semiconductor with an indirect band gap of 1.2 eV. Monolayer MoS2 has a band gap of ~1.8 eV. Molybdenum Disulfide is used for example as a photodetector and transistor. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. MoS2 belongs to the group-VI transition metal dichalcogenides (TMDC).

The 2H phase MoS2 crystals produced at HQ Graphene have a typical lateral size of ~0.8-1 cm, hexagonal/rectangular shaped and have a metallic appearance. We produce both n-type and p-type MoS2, having a typical charge carrier density of ~1015cm-3 at room temperature. A selection of peer review publications on the MoS2 crystals we sell can be found below.
