Decoupling epitaxial graphene from metals by electrochemical oxidation

The catalytic role of metallic substrates is a perfect starting point for growing high quality graphene layers by thermal decomposition of aromatics. However, metallic substrates quench the outstanding properties that make graphene the most promising material for future applications. Thus, protocols to transfer graphene to different technologically relevant substrates are…

On-surface chemistry: (cyclo)dehydrogenation of PAH catalysed by coinage metal surfaces

New nanoarchitectures can be built from polycyclic aromatic hydrocarbons (PAH) by exploiting the catalytic properties of some metal surfaces. Actually, this bottom-up approach allows the formation of nanostructures with different dimensionality from the same precursor as a consequence of the diffusion of the PAH on the surface. Thus, by selecting…

OPEN POSTDOCT POSITION AT THE ESISNA GROUP OF ICMM/CSIC

Functionalizing epitaxial graphene We are currently looking for a postdoc in the framework of the EC-Flagship program. The candidate should have proven experience in ultra high vacuum (UHV) and in some of the surface science characterization techniques (STM, LEED, XPS, synchrotron radiation…). IR experience in UHV will be advantageous. Your…

Diffusion controlled on-surface reactions: formation of N-doped nanoarchitectures

The bottom-up approach aims at forming tailored nanoarchitectures by manipulating organic molecules at atomic level and it is one of the most effective strategies used in nanotechnology. Catalytic surfaces are often used to prompt a particular reaction as they are very successful in modifying a particular molecule in selected ways.…
