"Graphene is the best known example of a two dimensional crystal. The spatial confinement of carriers movement into a single atomic plane and their linear energy dispersion results in a multitude of unusual electronic properties. Despite an intense research in recent years, there are still some unanswered questions concerning the electron-phonon interaction effects in this system. Also, the stacking the graphene flakes with other two dimensional crystals is known to have beneficial effects on its electronic properties, but little is known how it affects its magneto-optical response.
In my thesis, I present results of the micro-magneto-Raman scattering experiments that revealed new types of electron-phonon hybridization processes. I show how effects of electron-phonon interaction can be studied by resonantly switching it off and on. Finally, I present a significant improvement of the electronic quality of graphene deposited on BN, and how screening of electron-electron interaction affects its properties."
