Specification.

  • Identification. Full coverage 100% monolayer ReSe2 uniformly covered across c-cut sapphire
  • Physical dimensions. one centimeter in size. Larger sizes up to 2-inch wafer-scale available upon requests.
  • Smoothness. Atomically smooth surface with roughness < 0.15 nm.
  • Uniformity. Highly uniform surface morphology. ReSe2 monolayers uniformly cover across the sample.
  • Purity. 99.9995% purity as determined by nano-SIMS measurements
  • Reliability. Repeatable Raman and photoluminescence response
  • Crystallinity. High crystalline quality, Raman response, and photoluminescence emission comparable to single crystalline monolayer flakes.
  • Substrate. c-cut Sapphire but our research and development team can transfer ReSe2 monolayers onto variety of substrates including PET, quartz, and SiO2/Si without significant compromisation of material quality.
  • Support. 2Dsemiconductors USA is an American owned, regulated, and operated company. Our customers are well-protected by international as well as strict American customer laws and regulations. We give full technical support and guarantee your satisfaction with our well-established customer
  • Defect profile. ReSe2 monolayers do not contain intentional dopants or defects. However, our technical staff can produce defected ReSe2 using a-bombardment technique.
