WS2 Flakes

$199.00$229.00

Specifications:

  • Grown by chemical vapor deposition techniques
  • Flakes are single-crystalline and separated
  • Some conjoined flakes can be found with well-defined grain boundaries
  • Typical flake size ranges from 30 – 250 micrometers  (flake size is tunable upon request)
  • Prices are for standard 1 cm x 1 cm substrates
  • Standard substrates are SiO2/Si with 90 nm or 300 nm thermally grown oxide or single-side polished sapphire (others substrates available upon request)
  • For the monolayer product, most (> 70%) flakes are monolayers with some few-layer flakes co-existing.  Similarly, for the bilayer product, most (> 70%) flakes are bilayers, but some monolayers or few-layers can also be found. This contrast is easily distinguishable with optical microscopy.
  • Thicker flakes (trilayer or quadra-layer) can be found at the monolayer or bilayer product.
