The group of Integrated Devices and Systems (IDS) at the University of Twente (UT) is part of the Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) and the MESA+ Institute for Nanotechnology. MESA+ is the largest research institute of the UT. The institute trains graduate students and PhD-students and conducts research in the fields of nanotechnology, microsystems, materials science and microelectronics. Unique of MESA+ is its multidisciplinary composition.

The IDS group has a vacancy for a PhD student to work on photodiode detectors for photonic integrated circuits (PICS).

The aim of the project is to research and develop germanium photodiodes that are sensitive in a broad spectral range encompassing visual to short-wavelength light up to 1600 nm. The basic process will be a further development of our broadband Ge-on-Si “PureGaB” diodes that have been demonstrated with exceptional broadband responsivity and low dark currents. Concomitantly, the diodes should be modified to allow integration in an existing waveguide photonic circuit platform, and performance suitable for quantum computing circuits is aspired. The PhD will focus on the device fabrication and work with a postdoc for the design, characterization and optimization of the photodiodes. They will work closely with 2 PhD’s already studying the application of pure boron layers in other semiconductor devices.

This topic is part of a large European project with ten industrial and academic partners with a strong international reputation in PIC research. We strive to develop a unique PIC platform with functions enabled by hybrid integration of waveguides, detectors and lasers. The students have full access to state-of-the-art characterization equipment as well as the MESA+ Nanolab for experimentation.

Type of work: 50% experimental device fabrication, 30% material analysis, 20% optoelectronic characterization.

Your profile

  • You are highly motivated and an enthusiastic researcher.
  • You have a MSc degree in electrical engineering, nanotechnology, inorganic chemistry, applied physics or a related topic, with excellent theoretical and experimental skills.
  • You have proven affinity with materials science, preferably with semiconductors.
  • You have good team spirit and like to work in an internationally oriented environment.
  • You are proficient in English.

Our offer

  • As a PhD student at UT, you will be appointed to a full-time position for four years, with a qualifier in the first year, within a very stimulating and exciting scientific environment;
  • The University offers a dynamic ecosystem with enthusiastic colleagues;
  • Your salary and associated conditions are in accordance with the collective labour agreement for Dutch universities (CAO-NU);
  • You will receive a gross monthly salary ranging from € 2.541,- (first year) to € 3.247,- (fourth year);
  • There are excellent benefits including a holiday allowance of 8% of the gross annual salary, an end-of-year bonus of 8.3%, and a solid pension scheme;
  • A family-friendly institution that offers parental leave (both paid and unpaid);
  • You will have a training programme as part of the Twente Graduate School where you and your supervisors will determine a plan for a suitable education and supervision;
  • We encourage a high degree of responsibility and independence, while collaborating with close colleagues, researchers and other staff.
