CVD grown graphene was transferred on silicon substrate and transistor structured was formed with Cr/Au contacts. In this work, we used polzaniline (PANI), quatrothiophene (HEX) and perylene dicarboximide (PDI). Ink with these dyes consisted n-methylpyrrolidone (NMP), toluene, chlorobenzene as solvents and isopropanol as thickener. Prepared inks were printed with ink-jet printer Dimatix 3000.
