2H-MoTe2 (alpha phase MoTe2) is a semiconductor and a diamagnetic system with an indirect band gap of ~1.2 eV. Monolay 2H-MoTe2 have a direct band gap which is inversely proportional to the number of layers. It is a direct band gap material only for single layer or bilayer. Note that Molybdenum Ditelluride also exist in the 1T’ MoTe2 phase which is a semi-metal (for more information on 1T’ MoTe2 click here ). The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. MoTe2 belongs to the group-VI transition metal dichalcogenides (TMDC).

The α-MoTe2 crystals produced at HQ Graphene have a typical lateral size of ~0.6-0.8 cm, are hexagonal shaped and have a metallic appearance. The 2H MoTe2 is a n-type semiconductor, having a typical charge carrier density of ~1017cm-3 at room temperature.
