On-surface trapping of Ba ions by functionalized surfaces

Job Summary

We are seeking a postdoc with demonstrated experience in growth of organic materials in ultra-high vacuum (UHV) conditions and their surface science characterization techniques (as XPS, NEXAFS and STM). The candidate will explore the ion chelation mechanism of fluorescence molecules in contact with a surface and determine how the molecule-surface interaction affects the final emission of the organic molecules.

Job Description

This research is integrated in the framework of the BOLD project, funded by the European Research Council Executive Agency (Synergy Grant Agreement number 95128). This project contributes to the development of the NEXT international experiment (https://next.ific.uv.es/next/) which aims to detect by the first time neutrinoless double-beta decay. The confirmation of the existence of this type of reaction will be a major scientific achievement, with a very deep impact in some of the most important current Physics Models, like the Standard Model and the Big Bang. The final goal of the BOLD project is the development of a chemical sensor, able to capture Ba2+ dictation. This sensor is under exploration as potentially unique tools in the field of neutrino particle physics. The application of such chemosensors to the field of particle physics is totally novel and requires experimental demonstration of their suitability in the ultra-dry environment of a xenon gas chamber.

The candidate will join the Nanophysics Laboratory (NanoLab) in the Centro de Física de Materiales in San Sebastián (Spain) (https://cfm.ehu.es/nanophysicslab/), an experimental surface science group devoted to the study of structural, electronic, magnetic and chemical properties of nanostructures. The research will be carried out in collaboration with the other groups involved in the BOLD project, located at University of the Basque Country, Harvard, University of Manchester and the Donostia International Physics Center, and also interacting with the multidisciplinary teams of scientist and engineers who are in charge of developing, building and commissioning the NEXT detectors. We are looking for highly motivated candidates, who will join this world-class, thrilling environment with many opportunities for professional development.
