Figure 1d displays the Raman spectrum Figure 1 | Spectroscopic characterizations of a graphene/MoS2 bilayer. (a) Photo showing that a MoS2 monolayer was grown on the right hand side of the 300 nm SiO2/Si wafer followed by transferring graphene onto the bottom half. (b) Schematic illustration ...
. The graphene sheet was grown via a chemical vapor deposition (CVD) process on a copper foil56, and was transferred utilizing the PMMA-assisted method to ODTS-modified SiO2 substrates as the channels of GFETs. Monolayer graphene was identified by Raman spectroscopy (see ...
