Description
World's largest size commercially available 1T-TaS2 crystals
Our single crystal 1T-phase TaS₂, grown using the superior flux zone technique, guarantees CDW behavior and avoids the contamination issues of chemical vapor transport (CVT). Each growth produces highly crystalline, perfectly oriented (0001) crystals ready for exfoliation. Moreover, these crystals are environmentally stable for long-term use without air interaction concerns.
Flux zone vs. CVT growth method
If you research needs STM grade surfaces or even STM samples (flat crystals mounted on conductive STM holders) please contact us, we will be happy to arrange these samples.
