To remove the Cu substrate from the PMMA/graphene/Cu stack layer, the layer was transferred onto glass after wet etching and washing with water. For wet etching, we used an aqueous solution of ammonium persulfate ((NH4)2S2O8, Sigma-Aldrich). Finally, after air-drying, this process was repeated five times to produce five graphene layers (Fig. 4).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
