"better than van der Waals: stronger bonding,wider broadband optical detection especially from UV to near IR, enhanced optoelectronic intensity... overcomes MoS2 poor IR absorbance... 3 key features: (1) MoS2 large lateral size in µm range combined with ultrathin thickness <5 nm, (2) palladium nanosheets 2D morphology enables strong IR absorbance, (3) chemical connection between the 2 facilitated via bifunctional molecule... robust against solvents/ heat... medical monitoring, video imaging, optical communications"
