News Finding: In experiments, the researchers' wax-coated graphene performed four times better than graphene made with a traditional polymer-protecting layer.
Paper Finding: Similar to previous reports, our PMMA-transferred CVD monolayer graphene on Si/SiO 2 substrate experienced compressive strain and p-doping 30 .
News Context: Moreover, the coating can be washed away without leaving behind much residue. In experiments, the researchers' wax-coated graphene performed four times better than graphene made with a traditional polymer-protecting layer. "This technology is very useful, because it solves two problems simultaneously: the wrinkles and polymer residues."
Paper Context: In Fig. Similar to previous reports, our PMMA-transferred CVD monolayer graphene on Si/SiO 2 substrate experienced compressive strain and p-doping 30 . In contrast, our paraffin-transferred CVD monolayer graphene on Si/SiO 2 substrate experienced almost zero strain and very weak p-doping, approaching that of intrinsic graphene (Fig.
