My name is Alex and I just started my PhD in Physics in
superconductivity. I love the idea to work in a field which might change
our future to a greener one (loss less power grids, fusion plants,
energy storages for green energy) and combines basic research with
applications. I graduated from Vienna University of Technology but
studied some semesters abroad in Göttingen, Germany and at the High
Magnetic Field Lab in Tallahassee, Florida. I enjoy deepening my
knowledge and understanding of physics and traveling and experiencing
new cultures at the same time and I’m looking forward to a fruitful and
great time with all of you here at the ICMAB!

Crystal Growth and Design 15, 1957-1967 (2015)
The epitaxial growth of Ce0.9Zr0.1O2–y (CZO) thin-films on yttria-stabilized zirconia (YSZ) (001) single crystal and YSZ (001)/stainless steel (YSZ/SS) technological substrates is investigated by pulsed laser irradiation of solution-derived cerium–zirconium precursor layers using a UV Nd:YAG laser source at atmospheric conditions. The influence of laser processing parameters on the morphological and structural properties of the obtained films is studied by atomic force and transmission electron microscopies, as well as X-ray diffractometry. The analyses performed demonstrate that laser treatments enable the epitaxial growth of tens of nanometers thick CZO films with a crystallization kinetic process several orders of magnitude faster than that of conventional thermal annealing. Fully epitaxial films are attained using stainless steel (SS) flexible tapes as a substrate. Even though photochemical mechanisms are not fully discarded, it is concluded that photothermal processes are the main contribution responsible for the fast epitaxial crystallization.

Hello, my name is Alvaro Calleja, I’m an Electronic Design Engineer and I have just joined today the group of Superconducting Materials and Nanostructure at Large Scale at ICMAB. My tasks are related to the development of electronic control and monitoring systems for the project of Development of a New Generation of Electric Generators with Superconducting Coils, within of Teresa Puig’s group and under the supervision of Dr. Xavier Granados. See you around at ICMAB!
