產品簡介

供貨周期 一周    
Isolated monolayer thickness MoS2 are grown onto c-cut (0001) sapphire substrates.

詳細介紹

Isolated monolayer thickness MoS2 are grown onto c-cut (0001) sapphire substrates. This particular product contains monolayer thickness MoS2 triangular flakes randomly distributed across sapphire substrate. While some regions reach continuity with coalesced MoS2 triangles, this sample contains well-separated triangles for advanced spectroscopy, microscopy, and electronic measurements. Synthesized monolayer MoS2 triangles are highly luminescent and Raman spectroscopy studies also confirm the monolayer thickness.

Specifications

1)     Well-separated MoS2 domains across c-cut sapphire

2)     One centimeter in size. Larger sizes up to 2-inch wafer-scale available upon requests.

3)     Atomically smooth surface with roughness < 0.15 nm.

4)     Highly uniform surface morphology. MoS2 triangles are scattered across sample

5)     99.9995% purity as determined by nano-SIMS measurements

6)    Repeatable Raman and photoluminescence response

7)     High crystalline quality, Raman response, and photoluminescence emission comparable to single crystalline monolayer flakes.

8)     c-cut Sapphire but our research and development team can transfer MoS2 triangles onto variety of substrates including PET, quartz, and SiO2/Si without significant compromising of material quality.

9)    Defect profile. MoS2 monolayer triangles do not contain intentional dopants or defects. However, our technical staff can produce            defected MoS2 using α-bombardment technique.

 

 

Supporting datasets [for Monolayer MoS2 Triangles on c-cut Sapphire]

 

Transmission electron images (TEM) acquired from CVD grown MoS2 isolated triangles on c-cut sapphire confirming highly crystalline nature of monolayers

Energy dispersive X-ray spectroscopy (EDX) characterization on CVD grown MoS2 isolated triangles on c-cut sapphire confirming Mo:S 1:2 ratios

Room temperature photoluminescence spectroscopy (PL) and Raman spectroscopy (Raman) measurements performed on CVD grown MoS2 isolated triangles 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.
