Postdoc position for Sensitive Magnetotransport Measurements – DTU Energy

Danmarks Tekniske Universitet

Job description

Job Description:Do you want to contribute to a future where we can use novel magnetometers to understand diseases in the human brain by measuring the tiny magnetic fields created by neurons in the brain? In a joint project between DTU and KU we are targeting exactly this, and we are looking for a dedicated postdoc to conduct sensitive electrical measurements and develop new measurement schemes for extraordinary magnetoresistance & Hall magnetometers.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 is a top priority.In a large Novo Nordisk Foundation-sponsored project called Biomag, we aim to use 2D materials and III/V semiconductors to create novel 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 develop sensitive measurement schemes for extraordinary magnetoresistance & Hall magnetometers.Responsibilities and qualifications
You will work in a highly collaborative team composed of experimental and theoretical colleagues. Here, theoretical colleagues will predict the optimal sensor geometry and material properties for the given measurement scheme using novel topology optimization tools. The numerical designs will be experimentally realized using high-mobility graphene and III/V semiconductors in collaboration with device fabrication experts. You will then test the performance of the magnetometers and measurement protocols and feed your recommendations back to your colleagues. Lastly, you will also work together with neuroscience colleagues to detect live neurons.The main tasks are:

• Low-noise electrical characterization of Hall and extraordinary magnetoresistive magnetometers.
• Optimization of electrical characterization setups, hardware and software.
• Design of novel electrical measurement sensing schemes to lower the detection limit of single extraordinary magnetoresistive magnetometers and sensor arrays.
• Magnetometry measurements on neurons.

Required qualifications:
Qualified applicants must have:

• Extensive experience with low-noise electrical measurements and design of new sensing schemes, incl. extensive experience in noise-optimization of electrical setups, optimizing measurement protocols, and coding measurement software.
• Experience with micro- or nanoscale devices, ideally on 2D materials or III/V semiconductors.
• A keen interest in sensing ultra-weak magnetic fields to push the boundaries of all-electronic magnetic field sensors. Prior experience with low-noise magnetic sensors (Hall, magnetoresistive or NV magnetometers) is an advantage, but not a must.

General qualifications:

• A strong drive to move the frontiers of science.
• The ability to work independently, to plan and carry out complicated tasks, and to be a part of a large, dynamic group.
• Independent problem-solving skills.
• Excellent communication and language skills in English, both written and spoken.

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