This product contains MoSe2 monolayers on c-cut sapphire substrates. Sample size measures 1cm in size and the entire sample surface contains monolayer thick MoSe2 sheet. Synthesized monolayer MoSe2 is highly luminescent and Raman spectroscopy studies also confirm the monolayer thickness (please see the technical specifications), however few-layer regions are also anticipated to be observed.
