PhD: Next-Generation Quantum Thermometers using Ultra-Thin Microresonant Sensors

Research / Academic


The ability to accurately measure temperature with thermometers has revolutionized our understanding of science and is now an important capability in nearly every aspect of our technologies. As heat can be viewed as the vibrating motion of atoms in a material, the newest technologies aim to measure temperature at the level of single quanta of vibration (phonons). Micromechanical thermometers on a silicon chip are emerging as an exciting and powerful tool towards measuring temperature at this unprecedented quantum level. In this project, we will be further engineering the world’s best micromirror sensors to measure temperature at the quantum limit with lasers. This will also improve the accuracy of measurements, by facilitating traceablity to standards and fundamental constants of nature. Your task as a PhD will be to design novel nanostructures using computer simulations, bring your designs to life in a cleanroom and apply and test them in an optical setup for temperature measurements. 

It is expected that you will:

  1. Develop state-of-the-art micromechanical mirrors for quantum thermometry.  
  2. Design novel nanostructure structures using computer simulated models.
  3. Bring your new designs from simulation to reality at the nanoscale using cutting-edge cleanroom techniques.
  4. Build optomechanical characterization setups for nanophotonics.
  5. Write a doctoral dissertation, publish results in renowned peer-reviewed journals, and present research in international conferences.


Applicants should have the following qualifications:

  • MSc university degree in mechanical engineering, physics or a related area, with a solid background in dynamics, optics, MEMS or NEMS.
  • Experience in numerical modelling and analytical/computational tools. 
  • High motivation for teamwork and good communication skills. 
  • Experience in optical measurement techniques, experimental dynamics at the microscale and microfabrication are an advantage.
