ICN2 has been awarded with the Severo Ochoa Center of Excellence distinction for three consecutive periods ( and and ).
ICN2 comprises 19 Research Groups, 7 Technical Development and Support Units and Facilities, and 2 Research Platforms, covering different areas of nanoscience and nanotechnology.
Job Title.
Senior Researcher Research area or group.
Advanced Electron Nanoscopy Description of Group/Project.
The Catalan Institute of Nanoscience and Nanotechnology (ICN2) is currently seeking a highly motivated Senior Researcher to join Prof.
Jordi Arbiol's group.
The focus of this position will be on atomic scale scanning transmission electron microscopy (STEM) characterization of quantum materials and devices.
The PostDoc will engage in focused ion beam (FIB) sample preparation and utilize related analytical techniques such as energy-dispersive x-ray spectroscopy (EDS) and electron energy loss spectroscopy (EELS).
The research will involve advanced STEM-related (e.
..
4D STEM) atomic scale characterization of state-of-the-art semiconductor and hybrid (semiconductor/superconductor) devices for quantum applications (Qubits for quantum computing).
In-situ cooling experiments and data analysis automation will be integral to the project, with a particular emphasis on low-loss EELS and valence EELS (VEELS) bandgap mapping in hybrid semi-super heterostructures.
Join our dynamic group, leader in the atomic-scale characterization of semiconductor devices.
As part of our team, you'll have the opportunity to collaborate with a large network of quantum physics researchers worldwide and participate in the e-DREAM European microscopy network, which provides access to cutting-edge EM equipment and will allow you to participate in some of the largest EU projects related to STEM methodological development.
The project is funded by research project "Deterministic Quantum Dots for Quantum Photonics (DeQD)" financed by the Innovation Fund Denmark.
