Monolayer MoSe2 on c-plane Sapphire

CVD grown monolayer MoSe2 single crystals

Monolayer MoSe2 is a direct bandgap semiconductor (Eg = 1.57 eV), which is a promising material for several applications such as field effect transistors, photodetectors, solar cells, energy storage devices, catalysis etc. We grow high-quality MoSe2 single crystals on various substrates. The quality of the grown single crystals produced by our growth method is confirmed using several complementary characterization techniques, such as optical microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, Photoluminescence spectroscopy, High-resolution transmission electron microscopy etc.

Key characteristics

• High optical quality (George et al. 2020, 2D materials, Najafidehaghani et al. Adv. Func. Materials 2021))
• Good electrical characteristics (field-effect mobility ~ 30 cm2/Vs)
• n-type semiconductor

As grown

Standard Substrates: SiO2 on Si, c-plane Sapphire, Quartz (fused silica), Gold Single Crystal, Gold Foil
Size of the as-grown crystals: 5 µm to 100 µm in hexagonal or triangular or starlike shape

Customized samples

We can provide monolayer MoSe2 grown or transferred onto your choice of the substrate (e.g. Flexible substrates, silicon waveguides, optical fibers etc.). Contact our experts via email or telephone to discuss the options. Additional costs involved for customization services
