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

The flux zone growth technique produces higher quality crystals compared to the chemical vapor transport (CVT) method. Flux zone growth results in cleaner, more crystalline samples by minimizing contamination and defects commonly found in CVT-grown crystals. This method ensures superior structural integrity and purity, making it ideal for fundamental research and applications requiring high precision and reliability. The extended growth period in flux zone also allows for better control over crystal orientation and size, leading to consistently excellent crystal quality.

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.
