Do you want to work in the field of advanced materials and be involved in a high profile research project on the forefront of science? DTU Energy invites applications for a 1 year Postdoc to set up a micro four-point probe (M4PP) measurement emulator.

 

M4PP measurements offer a unique opportunity to observe thermoelectric transport phenomena in semiconductors. We will use this opportunity to investigate length-dependent heat and charge transport.

 

We wish to build a virtual measurement system, such that we can easily switch different physical phenomena on/off. With this, we can separate physical effects such as Seebeck effect, Hall effect, Joule heating, Peltier cooling/heating, etc., and we would be able to evaluate influence of different material properties and sample geometry on practical measurements. This will help us to identify measurement signatures of different nanoscale thermoelectric transport phenomena.

 

Responsibilities and tasks

You will be part of the national research project “Metrology for Energy and Electronic Materials” supported by the Danish Council for Independent Research. Measurements are performed on fully automated M4PP systems, and you will take part in developing new metrology methods to extract material properties with high precision, accuracy and spatial resolution.

 

In this Postdoc project you will set up time-dependent finite element models of four-point probe measurements for different sample geometries. You will export the simulated voltage respond and calculate amplitude and phase using a digital lock-in amplifier. Everything should be controlled via Matlab.

 

Once the system emulator is operational, you will compare predicted measurement signals with experimental data.

 

Qualifications
Candidates should have a PhD degree or equivalent.

 

We strive towards performing exceptionally precise and accurate measurements. Thus, in order to be successful in this project, you should be highly motivated and a fast learner. You should also be familiar with finite element method and Matlab.

 

Experience in one or more of the following will be an advantage:

  • Thermoelectric effects
  • Semiconductor device physics
  • COMSOL Multiphysics
You should have finished your PhD within the last 4 years.
