TaWSe2 Crystal

We offer high-purity, layered TaWSe2 ternary alloys synthesized with a 1:1 ratio of tungsten (W) to tantalum (Ta), bridging the properties of semiconducting WSe2 and metallic 2H-TaSe2. By alloying these two materials, we produce novel van der Waals (vdW) crystals with unexplored physical properties, available in bulk and monolayer form.

• WSe2: A direct bandgap semiconductor with strong excitonic binding energy and valleytronic features.

• TaSe2: A metallic phase exhibiting incommensurate charge density waves (CDW) and superconductivity below 1 K.

Why Our Crystals Stand Out: Growth Method Matters

We offer two growth methods. Unless specified otherwise, we ship Flux zone-grown crystals by default.

Flux Zone Growth (Default)

• Halide-free technique for semiconductor-grade crystals

• Slow crystallization over ~3 months ensures superior atomic ordering (crystals are in stock and ready to ship)

• Extremely low defect density: ~1×10⁹ – 1×10¹⁰ cm⁻²

• No contamination, making these ideal for electronic and optical applications

Chemical Vapor Transport (CVT) Growth (Upon request)

• Faster growth (~2 weeks) (crystals are in stock and ready to ship)

• May contain residual halides and point defects

• Higher defect density: ~1×10¹¹ – 1×10¹² cm⁻²

• Suitable for rapid prototyping or lower-cost studies
