Job Title: PostDoc - Quantum nanomaterials and hybrid semiconductor/superconductor heterostructures at the Atomic-Scale - ICN2 & ALBA Synchrotron

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 PostDoc 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.g.: 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.
