Tungsten Sulfide

World’s First 3R WS₂ Crystals  Introducing the world’s first 3R phase WS₂ crystals. The 3R phase of WS₂ refers to a rhombohedral crystal structure that differs from the more commonly...

Van der walls flakes (powdered crystals) of WS2 have been synthesized through high-pressure reaction at elevated temperatures. Each powdered domain consists of vdW layered WS2 sheets. These...

World's first molecular beam epitaxy (MBE) grown WS2 monolayers. MBE is an epitaxial method for single-crystal quality film deposition which offers high crystallinity and reduced defect density...

Isolated monolayer thickness WS2 are grown onto c-cut (0001) sapphire substrates.  This particular product contains monolayer thickness WS2 triangular flakes randomly distributed...

This product contains full area coverage WS2 monolayers on c-cut sapphire substrates. Sample size measures 1cm in size and the entire sample surface contains monolayer thick WS2 sheet...

Monolayer WS2 transferred on SiO2/Si substrates. Full area WS2 monolayers were synthesized first using our established CVD growth method on c-cut sapphire and transferred from sapphire onto SiO2/Si...

This product contains full area coverage WS2 few-layers that measure ~5 layers in thickness. Sheets are grown through chemical vapor deposition technique onto c-cut double side polished sapphire...

This product contains WS2 flakes solution in ethanol. The WS2 solution has been developed by ultrasonic treatment of bulk WS2 high quality crystals synthesized through vapor transport (CVT) technique...

Tungsten disulfide (2H-WS₂) crystals are extremely rare in nature and are less than 10 microns in the quartz / MoS₂ matrix. We are currently offering one of a kind naturally occurring...

High purtiy WS2 crystals have been I2 (iodine) intercalated to achieve p-type doping. Crystal size measures 0.5cm and larger in size and the product is ready for exfoliation

World record size WS2 crystals. We offer the largest size crystals at the highest quality possible. Our WS2 crystals are treated as gold standards in field. These WS2 vdW crystals are grown...
