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. 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.
