The IMTEK-Laboratory for Sensors is looking for a PostDoc
  • Bewerbungsfrist: 30.06.2023
  • Veröffentlicht: 22.05.2023
  • Start-date: At the earliest possible date.
  • Fulltime position
  • Kennziffer: 00003057


In the upcoming months a new research group will take over the Sensors Laboratory to be headed by Dr. Alwin Daus who will be an incoming Tenure-Track Professor at IMTEK, University of Freiburg.

Until now, Dr. Alwin Daus has been leading his own research group at RWTH Aachen University, specialized in two-dimensional (2D) material growth and flexible electronic devices. Dr. Daus’ research directions span a wide range including (flexible) sensors, transistors, memory, and solar cells.

He is mainly interested in research on emerging semiconductor materials, such as sputtered oxide semiconductors, chalcogenides and 2D materials, that can be integrated into devices at low process temperatures. This makes them compatible with a variety of substrates leading to exciting potential applications in Internet-of-Things, bendable displays, electronic skin, biomedical diagnostics, wearables, and environmental sensors. Furthermore, he is active in the research of devices for brain-inspired (neuromorphic) computing which could provide an energy efficient alternative to conventional hardware ideally suited for edge sensor systems or brain-machine interfaces.

If these topics have sparked your interest, you now have the opportunity to join Dr. Daus’ group as a postdoc where you can help shaping a new research direction at IMTEK, University of Freiburg.

In this postdoc position you will be able to gain valuable skills for a scientific career by working on the following tasks:

  • Cutting-edge research related to the topics mentioned above
  • Actively taking part in setting up the lab including decisions on purchase of new equipment
  • Providing guidance to doctoral, master and bachelor students and working in a diverse and international team
  • Gaining experience in teaching by assisting in lectures and/or exercises
  • Gaining experience in proposal writing
  • Engaging in international collaborations, building a greater network at international conferences, and publishing high quality research papers.

Your qualifications ideally include the following aspects:

  • Hold a PhD (or equivalent) degree from a reputable institution
  • Strong academic track record and aptitude towards explorative, experimental work
  • Published works in reputable journals or conferences
  • Experience in cleanroom device fabrication, semiconductor material synthesis and/or structural, chemical, and electrical device/material characterization
  • Prior work on sensors and/or flexible electronic devices is a plus
  • Excellent communication skills and fluent in written and spoken English, knowledge of the German language is a plus
  • Strong degree of scientific curiosity, independence, diligence and creativity are highly desirable
  • Embrace open and collaborative working culture and being an excellent team player.

If this description picked your interest, please contact Dr. Alwin Daus via email.
