Alexander Stangl

alexander stangl Hola! 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!

Ultrafast Crystallization of Ce0.9Zr0.1O2–y Epitaxial Films on Flexible Technical Substrates by Pulsed Laser Irradiation of Chemical Solution Derived Precursor Layers

cg-2015-001156_0010 A. Queraltó, A. Pérez del Pino, M. de la Mata, J. Arbiol, X. Obradors and T. Puig Crystal Growth and Design 15, 1957-1967 (2015) DOI: 10.1021/acs.cgd.5b00115 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.

2015-03-03_10-41-40 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!
