Electronic properties of graphene grain boundaries

Grain boundaries and defect lines in graphene are intensively studied for their novel electronic and magnetic properties. However, there is not a complete comprehension of the appearance of localized states along these defects. Graphene grain boundaries are herein seen as the outcome of matching two semi-infinite graphene sheets with different edges. We classify the energy spectra of grain boundaries into three different types, directly related to the combination of the four basic classes of spectra of graphene edges. From the specific geometry of the grains, we are able to obtain the band structure and the number of localized states close to the Fermi energy. This provides a new understanding of states localized at grain boundaries, showing that they are derived from the edge states of graphene. Such knowledge is crucial for the ultimate tailoring of electronic and optoelectronic applications.

Fiscal Integration in the European Union : assessment of different proposals

This paper explores the fiscal situation of the European Union as well as the different approaches proposed for achieving fiscal policy coordination among the member states. Furthermore, it works through the need of fiscal integration as a pressing matter in order for the European Union to achieve its aim of functioning as an efficient single market and economic unit. In order to do so, it analyzes the theoretical lines of the Modern Money Theory as a possible framework for further integration, and it evaluates the different proposals made for fiscal integration so that it can give an assessment regarding their compatibility with this theory.
