Reactivity of the TiO2(110) surface: deshydrogenating PAH’s by thermal activation

Our research group has shown the catalytic properties of the TiO2(110)-(1×1) surface towards dehydrogenation of large organic molecules. We have deposited C60H30 molecules on this surface and we have proven that high temperature annealing leads to partial cyclodehydrogenation, which allows the use of the activated PAH’s as building blocks for larger…

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.…

Strain-Driven Moiré Superstructures of Epitaxial Graphene on Transition Metal Surfaces

A simple model to explain graphene Moirés on single crystal metal surfaces Graphene revealed to be the most outstanding material of the decade. Scanning Tunneling Microscope (STM) images have proved the existence of Moiré superstructures on epitaxial graphene due to the spatial coincidence of the atomic periodicity of the graphene…

Surfaces: Magic wands for molecular transformations

New bottom-up strategies for molecular assembly to tailor-build new molecules The appearance on the technological scene of new electronic devices based on organic molecules is awaited with much expectation since they promise to be inexpensive, flexible, faster and smaller than those based on silicon technology. However, molecular electronics faces important…

An atomistic view of the the enantiomeric recognition of PAHs on single crystal metal surfaces

Recently published in Chemistry, a European Journal. Vacuum deposition of a planarized PAH, as C60H30 , on a single-crystal surface, as Pt(111), leads to surface induced chirality caused by the different landing side of the molecule, as depicted by in-situ STM images. We show that the surface discriminate the landing…

Ordered Vacancy Network Induced by the Growth of Epitaxial Graphene on Pt(111)

Published in Phys. Rev. Lett. by ESISNA Graphene is one of the most outstanding materials of the decade. Among all the different proposed applications and protocols to growth it, epitaxial graphene on single-crystal metal surfaces have acquired a significant relevance as a model system where to rationalize their atomic structure,…
