Electronic properties of graphene on a piezoelectric substrate

In the present work, we investigate theoretically the electronic propierties of a graphene layer on a piezoelectric substrate. Specifically, we study the efect of the surface acoustic vibration modes on the graphene electrons.This work is divided in six chapters plus several appendices whose goal is...

Sumario:In the present work, we investigate theoretically the electronic propierties of a graphene layer on a piezoelectric substrate. Specifically, we study the efect of the surface acoustic vibration modes on the graphene electrons.This work is divided in six chapters plus several appendices whose goal is to render the material as self-contained as possible. The rest chapter introduces a basic survey of the main actors in this work. Graphene is a two-dimensional material that has received increasin gworldwide attention since its isolation by Novoselov and Geim in 2004. It is formed by a honeycomb lattice of carbon atoms. Graphite, the most common form of pure carbon, can be viewed as made of weekly coupled graphene layers. The single-atom thickness of graphene, combined with its unique electronic properties stemming from the effectively massless behavior of electrons, converts this material into a special object of high fundamentaland applied interest...
