Energy dispersive X-ray spectroscopy (EDX) characterization on CVD grown full area coverage monolayer MoS2 on c-cut sapphire confirming Mo:S 1:2 ratios Room temperature photoluminescence spectroscopy (PL) and Raman spectroscopy (Raman) measurements performed on CVD grown full area coverage MoS2 monolayers on c-cut sapphire. Raman spectroscopy measurement confirm monolayer nature of the CVD grown samples and PL spectrum display sharp and bright PL peak located at 1.85 eV in agreement with the literature. Transmission electron images (TEM) acquired from CVD grown full area coverage MoS2 monolayers on c-cut sapphire confirming highly crystalline nature of monolayers Full Area Coverage Monolayer MoS2 on c-cut Sapphire Full Area Coverage Monolayer MoS2 on c-cut Sapphire

Full Area Coverage Monolayer MoS2 on c-cut Sapphire

SKU: CVD-MoS2-ML-SP
$490.00

This product contains full area coverage MoS2 monolayers on c-cut sapphire substrates. Sample size measures 1cm in size and the entire sample surface contains monolayer thick MoS2 sheet. Synthesized full area coverage monolayer MoS2 is highly luminescent and Raman spectroscopy studies also confirm the monolayer thickness.

Growth method: Our company synthesizes these monolayers using chemical vapor deposition (CVD) using highest purity (6N) gases and precursors in semiconductor grade facilities to produce crystalline and large domain size samples (1-50um). This is unlike commonly used MOCVD process wherein defects are very very large and domain sizes are small (10nm-500nm). Our samples are always highly luminescent and highly crystallized

Sample Properties

Sample size 1cm x 1cm square shaped
Substrate type (0001) c-cut sapphire
Coverage Full Coverage Monolayer

  • Identification. Full coverage 100% monolayer MoS2 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. MoS2 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 MoS2 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 service
  • Defect profile. MoS2 monolayers do not contain intentional dopants or defects. However, our technical staff can produce defected MoS2 using a-bombardment technique.
