Isolated monolayer thickness MoS2 are grown onto SiO2/Si substrates. This particular product contains monolayer thickness MoS2 triangular flakes randomly distributed across SiO2/Si 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. Overall, MoS2 monolayer thickness triangles are more luminescent compared to MoS2 triangles grown onto sapphire substrates.
