Postdoctoral research fellowship on spin-charge interconversion phenomena in oxide heterostructures - DTU Energy

The postdoc will fabricate SrTiO3 or KTaO3-based heterostructures and characterize samples in electronic transport experiments. Finally, the postdoc will evaluate the spin-charge conversion efficiency either by spin-injection transport or ferromagnetic resonance spin-pumping experiments.
Do you want to contribute to a future where we can create the new generation of electronic logic device?
At DTU Energy our research efforts are aiming at developing spintronic applications. Spintronics is a promising approach which goes beyond the operating principle in present-day electronics where the logic operation relies on the electron spin instead of its charge. Recently, heterostructures based on complex oxide systems have attracted a lot of interest in spintronics where the interconversion between electron spin and charge occurs through the spin-orbit coupling. Realising breakthroughs in such conversion phenomena will pave the way for a next generation of logic devices based on spin rather than charge.

The position offered is part of a new national project supported by the VILLUM Foundation. The project is carried out in close collaboration between DTU Energy in Denmark and international partners.

The objective of this project is to investigate the coexistence of a large spin-orbit coupling and electron mobility in oxide heterostructures and devices for spintronic applications. We hope that you are interested in joining this exciting project at the crossroads between physics, materials science, and logic device applications!

Responsibilities and qualifications

• PhD In Physics, Materials Science, Chemistry, Electrical Engineering or similar
• A strong background in applied physics/materials science
• Previous experience in low temperature measurements of physical properties such as electrical conductivity and/or magnetic properties is advantageous, but not a requirement.
• Previous experience in nano/micrometre device fabrication techniques, especially e-beam lithography is advantageous, but not a requirement.
• Previous experience in thin film deposition technologies, especially PLD and sputtering is advantageous, but not a requirement.
• Previous experience with field effect or quantum effects is advantageous, but not a requirement.
• Ability to work independently, to plan and carry out complicated tasks, and to be a part of a large, dynamical group
• Experience in programming, finite element modelling or writing measurement software is advantageous, but not a requirement.
• Good communication skills in English, both written and spoken

The work will be carried out in three stages: (1) You will fabricate complex oxide heterostructures based on SrTiO3 or KTaO3 by a combination of pulsed laser deposition (PLD) and sputtering. Herein, a device fabrication optimization with respect to electron mobility will be carried out with the aid of simple electronic transport characterization techniques. (2) The devices will be characterized in more advanced electronic transport experiments for establishing the spin-orbit coupling strength and (3) The spin-charge conversion efficiency will be evaluated either by spin-injection transport or ferromagnetic resonance spin-pumping experiments.

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