PtSe2 vdW crystals by 2Dsemiconductors
Platinum diselenide (PtSe2) is a type-II Dirac semimetal belonging to transition metal dichalcogenide (TMDCs) family with the MX2 formula. While it is an established semimetal in the bulk form the band gap of its monolayer has been recently predicted to be a semiconductor (Nano Letters, 2015, 15, 4013).
 
We produce world's largest commercial PtSe2 crystals using our flux zone growth technique. Our crystals are guaranteed to outperform any other commercial source PtSe2 in electronics, optics, vibration, and transport. Purity is confirmed at 7N or higher which is also the best in the field. 

The properties of flux zone growth PtSe2 crystals 

Sample size A few 2-3 mm sized vdW crystals
Material properties Semi-metal or semiconductor depending on thickness & catalytic material
Crystal structure Hexagonal phase a=b=0.379 nm, c=0.515 nm
