I propose the theoretical and experimental study of weak localization in graphene samples fabricated by different methods. For the theoretical study, we will apply existing models based on Green’s functions and the Kubo formula for the optical conductivity. for the experimental study, we will perform magneto-spectroscopy measurements in the microwave range. From the analysis of measurements, it will be possible to determine the main sources of impurities the samples, in an alternative approach compared to traditional methods.
