Graphene

Graphene, a 2D monolayer of carbon atoms, has witnessed a dramatic increase in research efforts given its remarkable physical properties. This is a zero gap semiconductor with a linear energy band dispersion around the Fermi energy (EF), so that the charge carriers mimic massless Dirac fermions.  As we are interested in the application of graphene in semiconductor devices, it is necessary to have a band gap in order to switch the conductivity between an on and off state. For this reason we intensively focus on physical and chemical approaches to resolve the topics under discussion within the community, from a spectroscopy point of view.

 

Graphite and Graphite Intercalation Compounds

 

Graphite intercalation compounds (GIC) have long been the focus of intensive research for several years.   Various techniques have been used to determine the structural information on the staging, molecular intercalant structure and layer separation in such layered structures. We are interested in performing Angle-Resolved Photoemission Spectroscopy and Raman spectroscopy of GIC to understand the solid state properties of these materials particularly appealing for applications.
