Postdoc in Atomic level 3D Mapping of Impurities in Quantum Materials DTU Nanolab

Are you eager to explore and advance the frontiers of atomic-scale 3D mapping of impurities in quantum platforms DTU Nanolab offers a unique opportunity to do so within an international and cutting-edge scientific environment working in a world-class cleanroom and developing techniques using a state-of-the-art electron microscopy facility.

We invite applications for a 2-year postdoctoral position focused on atomic-level 3D characterization of impurities in quantum materials using a plethora of transmission electron microscopy techniques e.g. exit wave reconstruction HR-STEM focal series 4D-STEM etc.

Precise spatial control and characterization of individual defects in crystals remain a critical challenge in the fabrication of quantum technologies. Supported by the Villum Experiment Programme this exploratory project aims to overcome this bottleneck through an innovative approach: combining controlled defect creation via focused ion beam with diffraction-based three-dimensional mapping. The project will further investigate diffusion pathways and activation kinetics by real-time inspection of defects behavior at elevated temperatures in controlled gaseous environments. The results will be corroborated with molecular dynamic simulations as well as first-principle calculations.

At DTU Nanolab we offer:

• A leading international research environment with access to state-of-the-art electron microscopy facilities.
• A collaborative and interdisciplinary atmosphere that encourages integration of theory and experiment.
• Opportunities to contribute to the development of innovative methodologies in materials characterization.
• Support for career development and international networking in a diverse and welcoming working environment.

Responsibilities and qualifications
Your overallfocus will be on developing and exploring a novel platform for reliable three-dimensional mapping of impurities and/or defects in materials for quantum technologies.
We are looking for a highly motivated candidate with experience in:

• Focussed Ion Beam (FIB); e.g. ion implantation/ TEM sample preparation.
• Electron Beam Lithography (EBL).
• Molecular Dynamics (MD) simulations.
• Electron Microscopy simulations e.g. abTEM or other first-principle calculations platforms.

As a formal qualification you must hold a PhD degree (or equivalent).
