Highly crystalline epitaxial Ba0.8Sr0.2TiO3 (BST) thin-films are grown on (001)-oriented LaNiO3-buffered LaAlO3 substrates by pulsed laser irradiation of solution derived barium-zirconium-titanium precursor layers using a UV Nd:YAG laser source at atmospheric conditions. Thestructural analyses of the obtained films, studied by X-ray diffractometry and transmission electron microscopy, demonstrate that laser processing allows the growth of tens of nm-thick BST epitaxialfilms with crystalline structure similar to that of films obtained through conventional thermal annealing methods. However, the fast pulsed nature of the laser employed leads tocrystallization kinetic evolution orders of magnitude faster than in thermal treatments. The combination of specific photothermal and photochemical mechanisms is the main responsible for the ultrafast epitaxial laser-induced crystallization. Piezoresponse microscopy measurements demonstrate equivalent ferroelectric behavior in laser and thermally annealedfilms, being the piezoelectric constant ∼25 pm V−1.
From 18th May to 17th July 2015, Juan Carlos Gonzalez has visited Prof. Renner’s group at Département de Physique de la Matière Condensée, Université de Genève, Genève (Switzerland) to perform some experiments on “Scanning Tunneling Microscopy of Resistive Switching phenomena in La1-xSrxMnO3-x compounds” under the supervision of Dr. Ivan Maggio-Aprile.

“Este año, Teresa Puig es la única investigadora española que ha conseguido una Advanced Grant del Consejo Europeo de Investigación (ERC)”
Otros 12 colegas hombres han logrado también esta prestigiosa financiación de la Unión Europea, destinada a directores de investigación. Estas y otras ayudas del ERC son muy competitivas y suelen ser un referente de quiénes son los investigadores y los centros más competitivos de un país.”

EL PAÍS:
“Solo uno de cada 10 investigadores galardonados en la última edición de las Advanced Grants del Consejo Europeo de Investigación (ERC) es mujer. La diferencia entre sexos registrada este año es aún mayor de lo habitual. En España, entre los 13 investigadores que han conseguido este apoyo financiero, solo hay una mujer: Teresa Puig, del Instituto de Ciencia de Materiales de Barcelona.”

“Guardons que aportaran prop de 13 milions d’euros a tres dels grans centres d’investigació de Catalunya gràcies a cinc dels seus científics: Teresa Puig, de l’Institut de Ciències Materials de Barcelona (ICMAB); Niek van Hulst, de l’Institut de Ciències Fotòniques (ICFO); Lluís Serrano, James Sharpe i Juan Valcárcel, del Centre de Regulació Genòmica de Barcelona (CRG).”
Hi there,
I’m Cristiano, I’ve got my master degree in Supramolecular chemistry in Italy at the University of Pavia. I’ve joined the ICMAB on July as a scholarship holder. Right now I’m working in the Superconducting Materials and Nanostructures at Large scale Group. My work deals with polymer assisted deposition of magnetic oxide films.
see you around then!!!
