(a) Raman spectra of 2DrGO and 3DrGO (dashed line: G peak at 1592 cm−2 and 2D peaks at 2680 cm−2). (b) Intensity ratios for 2DrGO and 3DrGO (black arrow: ID/IG ratio, blue arrow: I2D/IG ratio). (c) XPS analysis of 3DrGO with 2DrGO in the inset. (d) Ids–Vds characteristics for the interdigitated 2DrGO- and 3DrGO-based devices; inset: resistance of the samples.
