Chemically-Linked Heterostructures of Palladium Nanosheets and 2H-MoS2

The burgeoning field of 2D heterostructures targets the combination of 2D materials with 3D, 1D, or 0D nanomaterials. Among the most popular 2D materials, the 2H polytype of molybdenum disulfide (MoS2) features a well‐defined bandgap that becomes direct at the monolayer level, which can be exploited...
