Enhanced photoconductivity of semiconductor polymers using graphene nanoflakes
We have examined the effect of the addition of graphene nanoflakes (GNs) to improve the field-effect mobility of poly(3-hexylthiophene) (P3HT)-based field-effect transistors (FETs). We observe that the FET mobility increases up to 0.02 cm2/Vs at GNs concentration of 0.06 mg/mL. The remarkable … Continue reading
