Low dimensional materials

This research line focuses on the study of graphene and other 2D materials (graphene and beyond). Our group is pioneering in the synthesis of epitaxial graphene on metals substrates and in its characterization at the atomic level. From 2014 the group participates in the EU Graphene Flagship Project and new research sublines have been added to understand and overcome new related-graphene phenomena.

The on-going research lines are:

1. Synthesis and characterization of graphene


Graphene growth by Physical Vapor Deposition (PVD) on metal substrates and characterization of graphene moieties, the origin of the «Moiré» patterns (coincidence networks) and the interaction with the substrate at the atomic level are some of the studies here develop.


2. Intercalation, decoupling & interface


This subline focuses in the development of novel intercalation and decoupling strategies in 2Ds including electrochemical and photo-induced protocols. We perform a characterization of the structural, chemical and electric properties of the alkali/graphene interface


3. Covalent Functionalization of 2Ds &  biosensing applications


We have developed a highly controlled covalent functionalization protocol with outstanding versatility that can be used in a huge variety of applications. Currently we have been working in the functionalization of graphene-FETs to be used as graphene biosensors for virus detection.
