Atomic–layer–confined multiple quantum wells enabled by monolithic bandgap engineering of transition metal dichalcogenides (Prof. Gwan-Hyoung Lee’s group)

 

Professor Chul-Ho Lee group (Korea University) and Gwan-Hyoung Lee group (Seoul National University) collaborated to fabricate atomic-layer-confined multiple quantum wells via monolithic bandgap engineering. Layer-by-layer oxidation of bilayer WSe2 into WOx/WSe2 heterostructure formation of type I band structure. Atomic-layer-confined multiple quantum wells showed superlinear enhancement of photoluminescence with increasing number of quantum wells. This work was published on Science Advances by AAAS (American Association for the Advancement of Science).
