Abstract :
The electrical properties of solution-processed composite thin films, consisting of functionalized graphene sheets (FGS) as the filler and polystyrene (PS) as the host material are described. We demonstrate that transistors from graphene-based composite thin films exhibit ambipolar field effect characteristics, suggesting transport via percolation among FGS in the insulating PS matrix. Device characteristics as a function of the [1]FGS size are also reported. The results indicate that devices fabricated using the largest size FGS yield the highest mobility values. This simple and scalable fabrication scheme based on a commodity plastic could be useful for low-cost, macro-scale electronics.
