Large-scale graphene films enable the integration of field-effect transistor (GFET) arrays onto chips. However, transfer characteristics display variability across array. This significant statistical variation in quality combined with lack standardized protocols poses a major challenge to commercialization. In this study, we present rapid, extensive, and high-resolution inspection technique using slit-scanning Raman microscopy. imaging all GFETs was performed before conducting electrical measurements. The G-band 2D-band peak positions were used determine hole carrier density (nH) GFETs. Variations nH values correlated VDP values, which is critical parameter FET performance, validating approach as an method. Moreover, peaks tracked 100 at different processing stages, revealing that spatial variations originated during wet-transfer process. method vital for scalable manufacturing devices.
