1T'-MoTe2 ( 1T' Molybdenum Ditelluride)

1T MoTe2 Molybdenum Ditelluride 1T'-MoTe2 is a Weyl semimetal and is paramagnetic. The layers in the beta phase MoTe2 are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. β-MoTe2 belongs to the group-VI transition metal dichalcogenides (TMDC). Note that MoTe2 also exist in the 2H-MoTe2 phase which is a semiconductor (for more information on 2H MoTe2 click here ). To buy MoTe2-1T crystals please click here.

The 1T' phase MoTe2 crystals produced at HQ Graphene have a typical lateral size of ~0.6-0.8 cm, rectangular shaped and have a metallic appearance. More information about the MoTe2 crystals we sell can be found below.
