Born in Barcelona (Spain) in 1976. I graduated at chemistry in the Universitat de Barcelona in 1998 and obtained my PhD in 2004 in the same university under the direction of Prof. Francesc Illas, working in magnetic properties of high-Tc superconducting cuprates and manganese oxides. I am currently working in the department of Physics & Astronomy of the University College of London since december of 2004 as a postdoctoral research assistant.
My research is focused on two main areas. One is the modelization of defects in the oxides HfO2 and ZrO2 and study of their electronic structure and related properties. ZrO2 shows useful mechanical, thermal, optical and electrical properties and has a broad range of applications in coatings, sensors and catalytic processes, while HfO2 has been postulated as possible material for the gate dielectric in field effect transistors. The presence of defects in their cristalline structure affect the properties and utility of these compounds in a way which is still not clearly understood.
The other topic of research involves the study of the compound 12CaO.7Al2O3 (C12A7) which features many different phenomena. The unit cell of this compound is organized in a positively charged framework of cages and a extra-framework species hosted in some of these cages; depending on the nature of these species, several interesting phenomena have been observed, like a transparent conductor phase. Due to the complex structure of this compound, the understanding of the experimental data is a difficult task that needs the help of theoretical models. Further information on C12A7 can be found here.
These studies are being carried out through the use of periodic and embedded cluster models of these compounds, in order to achieve a more complete understanding of their properties.
