CAS 12067-46-8 Molybdenum Tungsten Diselenide Alloy (MoWSe2)

Description

Description MoWSe2 alloy is a semiconductor. We have many different types of MoWSe2 alloys available containing a different ratio of Mo/W: ranging from alloys that are rich in Tungsten (close to 2H-WSe2) to alloys with a high Molybdenum content (close to 2H-MoSe2). The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. Molybdenum Tungsten Diselenide alloy belongs to the group-VI transition metal dichalcogenides (TMDC).

Features And Benefits

Features And Benefits The MoWSe2 crystals produced have a typical lateral size of ~0.6 cm, are hexagonal shaped, and have a dark metallic appearance.

Application

Application 2H-WSe2 nanosheets and particles play an important role in device applications such as transistors, photodetectors, light emitting diodes, photovoltaic solar cells, and in biomedical and photothermal therapies.
