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…
On-surface synthesis of cyclic organic molecules
A tutorial Chemical Society Review On-surface synthesis can be regarded as an efficient means to build new molecular species by using bottom-up strategies. Recently, a collection of different reactions leading to large tailor-made organic molecules on single-crystal metal surfaces has been reported. The fundamental mechanisms controlling these reactions can be…
The Welch Scholarship of the I.U.S.V.T.A.
Scholarship Application Deadline Extended to April 30th 2011 The Welch Scholarship provides $15000 support once per year to a promising scholar who wishes to study vacuum science, techniques or their application in any field, and wants to spend a year in a research lab in another country. This is an…
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,…
How are the STM images influenced by structural changes in the tip?
What you see it is not what it is! Chemical and morphological changes in the tip are frequent during an experimental STM session. We have shown the effect of different tip apexes on the appearance of atomic features of STM images by relating experimental STM images with DFT calculations. The…
