PhD student for studying spin-charge conversion phenomena in oxide heterostructures

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. As the material choice for the next stage of spintronics we are aiming at apply freestanding oxides which are characterized by radically new properties and functionalities.

We currently have an opening for a PhD-student to participate in developing freestanding oxide membranes with desired spintronic properties. The position is supported by a PhD scholarship from DTU within the Nordic Five Tech alliance. The project is carried out in close collaboration between DTU Energy in Denmark and Chalmers University of Technology in Sweden.

The objective of this project is to investigate the electronic properties of freestanding oxides in conjunction with spin-charge interconversion phenomena that is important 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

The work will be carried out in three stages: (1) The student will fabricate freestanding complex oxides devices based on SrTiO3 or KTaO3 by a combination of pulsed laser deposition (PLD) and sputtering techniques. Herein, a growth optimization with respect to crystalline quality of SrTiO3 or KTaO3 will be carried out with the aid of simple electronic transport characterization techniques. (2) The samples 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.

You must have a two-year master's degree (120 ECTS points) In Physics, Materials Science, Chemistry, Electrical Engineering or similar, or a similar degree with an academic level equivalent to a two-year master's degree.

Further qualifications:

• A strong background in applied physics/materials science
• A strong background in thin film technologies, especially PLD and sputtering
• Previous experience in low temperature measurements of physical properties such as electrical conductivity and/or magnetic properties
• 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

Approval and Enrolment

The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see
