Postdoc in extraordinary magnetometry using high-mobility semiconductors DTU Energy

Do you want to contribute to a future where we can use high-mobility materials to understand diseases in the human brain by measuring the tiny magnetic fields created by neurons in the brain At DTU we are targeting exactly this and we are looking for a dedicated postdoc to carry out research in high-performance extraordinary magnetoresistance and Hall magnetometers based on high-mobility semiconductors.

It is possible to get a deeper understanding of how the brain functions in a non-invasive way through sensing the tiny magnetic fields produced by neuronal currents. Today this need is primarily met by quantum sensors that must be operated at cryogenic temperatures which greatly increases the complexity and cost of making such measurements. Therefore research on alternative methods to detect tiny magnetic fields are a top priority.

In a Novo Nordisk Foundation sponsored project we aim to create magnetic sensors with picotesla sensitivity and use these sensors to map neuron activity at room-temperature. As part of this large project we are looking for a postdoc to help us fabricate and characterize high-mobility magnetoresistive devices and turn these into high-performing magnetometers.

Responsibilities and qualifications
The primary tasks will be:

• Batch fabrication of extraordinary magnetoresistive devices from high-mobility III/V semiconductors with novel geometric designs.
• Magnetotransport characterization of the devices.
• Control the trajectory of electrons in condensed matter.
• Assess the potential of the new magnetoresistance class for highly sensitive magnetometers.

You will work in a large team and must therefore both thrive with team-based research as well as contribute to a productive and pleasant research environment. During the project you will work closely together with colleagues in theory who propose optimized designs for your devices and both receive and provide help to fellow colleagues performing the experiments. You will also have the opportunity to carry out your own simulations with our numerical model.

Qualified applicants must have:

• Extensive experience with cleanroom fabrication of electrical devices based on high-mobility III/V semiconductors.
• High level of understanding of material science and electrical transport physics.
• Experience with electrical characterization of devices ideally low-noise characterization of magnetometers.
• A strong drive to move the frontiers of science.
• Structured work attitude and ability to plan and carry out sophisticated research activities.
• Excellent communication skills in English both written and spoken.

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