Abstract
The electronic properties of GO and RGO thin films can be tuned by varying the coverage of functional groups, chemical composition, film thickness and morphology, and average flake size. By appropriately tuning the deposition and reduction parameters, the GO/RGO films can be made insulating, semiconducting, or semimetallic. The tunable and controllable electronic properties of GO films enable their promising applications in electronic devices. The transparent and conducting properties of RGO can be also utilized in transparent conductors. Moreover, the excellent mechanical properties of GO films are useful for flexible electronic materials. On the other hand, as discussed in Chap. 3, GO processes outstanding optical properties. The intrinsic fluorescence of GO in wide regions leads to applications as optical sensing and detecting. The nonlinear optical properties of GO can be utilized for optical-limiting materials and saturable absorbers. Finally, existence of functional groups also brings about excellent behavior in surface enhanced Raman scattering (SERS) of GO.
