Wet chemical approach for one-step graphene transfer (OSGT) and modified one-step graphene transfer (MOSGT). Graphene surfaces were coated with PMMA at 4000 rpm for 1 min, placed in APS 100 Cu etchant for 8 hours, then rinsed in deionized water for 12 hours. Transparent substrates (sapphire and germanium) were surface-treated by chemical or plasma oxidation. Germanium was plasma functionalized in Ar or O₂ for 1 minute. Sapphire was immersed in SC₁ solution (DI H₂O:H₂O2:NH₄OH 6:1.5:1 at 80°C) for 10 min, HF etched for 1 min (49% HF in H₂O 1:100), then SC₂ incubated (H₂O:H₂O2:HCl 7:1.5:1 at 80°C) for 10 min.
