• PbSnS2 is a ternary compound  composed of stochiometric quantities of Lead and Tin. PbSnS2 is semiconducting. Atomically thin layers have yet to be isolated and characterized.
  • Gallium selenide is a direct gap semiconductor.  We offer GaSe pieces ranging from sub-mm to 5mm. Each order comes with 100mg of material, enough for many exfoliations. The cryst
  • Single crystals of black phosphorus (phosphorene or BP) for graphene-like exfoliation. Item includes one crystal with minimum dimensions of 5mm x 5mm or equi
  • Single-crystals of mica with extremely large dimensions. The crystals are layered and cleavable, similar to graphite and may be used to produce atomically thin sheets of mica.  We
  • A single piece of large single-crystal graphite-graphenium crystals with minimum dimensions of 15mm x 15mm. Our crystals are natura
  • Tungsten ditelluride, (WTe2), is another member of the two-dimensional transition metal dichalcogenide family. In contrast with other materials, t
  • Single crystal WSe2 for mechanical exfoliation. The crystal measure a minimum of 3mm x 3mm in lateral dimensions and approximate thickness of 0.1mm.
  • Single crystal WS2 for mechanical exfoliation. The crystal measure a minimum of 3mm x 3mm in lateral dimensions.
  • Single crystal MoSe2 for mechanical exfoliation. The crystal measure a minimum of 3mm x 3mm in lateral dimensions and approximate thickness of 0.1mm.
  • Natural single-crystal molybdenum disulfide flakes, with domain sizes of the order of centimetres. The crystals may be exfoliated with scotch tape to produce atomically thin layers of MoS2 or used in STM measurem
  • Synthetic hexagonal boron nitride (hBN) single-crystals  with single-crystal domains exceeding 500 micrometers,  offered in two grades.
