Electroluminescence from vertically stacked GaN–Al2O3–MoS2–Al2O3-graphene heterostructures.
1st demo of electroluminescence from multilayer molybdenum disulfide, or MoS2, a discovery that could lead to a new class of materials for making LEDs. In its single-layer form, Mos2 is optically active, meaning that it emits light when electric current is run through it or when it is shot with a nondestructive laser. Multilayer molybdenum disulfide, by contrast, is easier and less expensive to produce, but it is not normally luminescent. In the new study, Duan and Dehui, created the 1st multilayer device that shows strong luminescence when electrical current is passed through it.
“It was rather surprising for us to discover that similar vertical devices made of multilayer MoS2 somehow showed ...
