CAS 12067-46-8 Tungsten diselenide Powder WSe2 used to make thin-film solar cells​

 

Breif introduction of  Tungsten diselenide Powder WSe2

 

Tungsten diselenide is an inorganic compound  with the formula WSe2.

 

The compound adopts a hexagonal crystalline structure similar to molybdenum disulfide. 

 

Every tungsten atom is covalently bonded to six selenium ligands in a trigonal prismatic coordination sphere while each selenium is bonded to three tungsten atoms in a pyramidal geometry.

 

The tungsten–selenium bond has a length of 0.2526 nm, and the distance between selenium atoms is 0.334 nm.

 

Layers stack together via van der Waals interactions. 

 

WSe2 is a very stable semiconductor  in the group-VI transition metal dichalcogenides.
