FUW MBETMD Monolayer (IMAGE) University of Warsaw, Faculty of Physics Caption Cross-section (top), luminescence (left), and atomic force microscopy image (right) of a MoSe2 monolayer grown using molecular beam epitaxy on hexagonal boron nitride substrate. Narrow lines in luminescence spectrum shows high optical quality of the layer.
