The increase in hard X-ray brightness in third generation synchrotron sources together with the development of fast two-dimensional X-ray detectors has enabled to perform time-resolved X-ray scattering experiments in the millisecond regime. Thus, the evolution of the thin film morphology at the nanoscale can be continuously monitored employing Grazing Incidence…
Recently, we have published a new work in a special issue of the Surface Science journal in Honour of Richard Lambert. “Adsorption and coupling of 4-aminophenol on Pt(111) surfaces” Surf. Sci. 646 (2016) 5-12 by G. Otero-Irurueta, J.I. Martínez, R.A. Bueno, F.J. Palomares, H.J. Salavagione, M.K. Singh, J. Méndez, G.J.…
Graphene growth on metal surfaces is one of the most promising routes towards scalable production of high-quality graphene suitable for industrial applications. Conventionally, the growth of graphene is carried out on weakly interacting surfaces – typically Cu foils – where the substrate plays a double role: first, as a catalyst;…
Here, we present experimental and theoretical evidence of a new reversible transition that takes place in Sn/Si(111):B. The system changes from an insulating (2 √ 3 × 2 √ 3)R30º structure at room temperature to a (√ 3 × √ 3)R30º symmetry above 520 K (2 √ 3 and √…
Surface nano-patterning by ion beam sputtering (IBS) is a bottom-up strategy to produce nanostructures on large areas of a wide range of materials (metals, insulators, semiconductors) in just a few minutes. This technique has been known for many years but its underlying physical mechanisms are still open to discussion. Initially,…
A deep and detailed understanding of the organic molecule – substrate interaction at the nanoscale is essential in order to develop a real nanoelectronic technology. The combination of Organic molecules and TiO2 surface is becoming a hot topic due to the extended use in novel photovoltaic devices. With this in…
One of the most extended approaches in order to growth metal-organic nanostructures on surfaces consists in recombine small organic molecules with a carefully controlled quantity of metallic atoms on a surface. As an example, our group followed this strategy in previous works for obtaining a rich variety of nanostructures by…
One of the most important research lines carried out by the ESISNA group is devoted to the characterization by the most advanced Surface Science techniques of the deposition of organic molecules on metal and metal oxide surfaces towards the formation of new molecular nanoassemblies and other hierarchical nanostructures. Following this…
Due to its exceptional conduction properties, graphene has been proposed as a candidate to replace silicon in future electronics. However, several problems need to be overcome prior to its implantation in the production chain. Among these difficulties, one of the most fundamental unknown aspects is how to contact graphene with…
