The mission of the Catalan Institute of Nanoscience and Nanotechnology (ICN2) is to achieve the highest level of scientific and technological excellence in Nanoscience and Nanotechnology. Its research lines focus on the newly-discovered physical and chemical properties that arise from the behavior of matter at the nanoscale. ICN2 has been awarded with the Severo Ochoa Centre of Excellence distinction for two consecutive periods (2014-2018 and 2018-2022). ICN2 comprises 19 research groups, 7 technical development and support units and facilities, and 2 research platforms, covering different areas of nanoscience and nanotechnology.
This is a call for expressions of interest from excellent postdoctoral researchers to apply for a Marie-Skłodowska-Curie Postdoctoral Fellowship with ICN2 as host institution. Specifically, we are inviting expressions of interest for the following research group and project.
DESCRIPTION OF HOST RESEARCH GROUP
Host group: Phononic and Photonic Nanostructures
Group Leader: ICREA Prof. Clivia Sotomayor Torres
Project supervisor: Dr. Francesc Alzina, Senior Researcher
The Phononic and Photonic Nanostructures Group (P2N) at ICN2 (https://www.icn2-p2n.eu) is an international team performing research at the cross roads between nanotechnology and dispersion relation engineering. The P2N group with its group leader has contributed to setup a community on phononics in Europe promoting and participating in many initiatives and projects. These contributions span over the phonon spectrum from phonons in the hypersound to thermal phonons, studying the effects of size reduction, periodicity and disorder, for the manipulation and control of phonons and heat management. The P2N group has also been successful in merging its expertise in optical processes in nanostructures and phononic and photonic engineering to implement hybrid optomechanical systems. This research is anchored in pioneering nanofabrication performed in our group and by collaborators. Candidates will benefit of a strong support during all the grant application process and the experience gained from our considerable success with applications in former MSCA-IF calls.
DESCRIPTION OF RESEARCH PROJECT / TOPIC
Research area: Engineering (ENG), Physics (PHYS)
Project topic: Electromechanical metasurfaces for wave generation and processing in the microwave-terahertz range
Following our central work on confined elastic waves in ultra-thin membranes or Lamb waves, we have studied two-dimensional (2D) phononic crystal (PnC) silicon membranes by combining different strategies, such us periodic modulation of the elastic constants, and local resonances, in order to change the dispersion of acoustic phonons. We have shown direct experimental evidence of the modification of the dispersion of GHz phonons propagating in the considered PnCs .
The candidate will work in a novel approach where the coupling of microwave-terahertz electromagnetic waves and mechanical modes should lay the foundations of new generation and processing capabilities in this spectral range.
We are seeking candidates interested in a joint proposal related to Electro-mechanical systems design, fabrication and characterization. Applicants should have strong background in nanofabrication techniques, electrical engineering or similar.
We also welcome proposal related to theoretical modelling and simulations. Applicants should have a strong background in at least one of the following areas: solid state physics and classical mechanics.
