Ph.D. student (F/M)

The group of Semiconductor Components at the University of Twente is part of the Faculty of Electrical Engineering, Mathematics and Computer Science and the MESA+ Institute for Nanotechnology. MESA+ is the largest research institute of the University of Twente. 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 group of Semiconductor Components has a vacancy for a Ph.D. student in the project “Towards polycrystalline GaN/AlGaN devices”. The project aims to investigate the properties of polycrystalline GaN and AlGaN materials for applications in semiconductor devices. Polycrystalline materials are easier and cheaper to make than monocrystals, but very little has been reported about this material in the literature so far. The group of Semiconductor Components is now recruiting for a PhD student who will address modelling and simulation aspects of polycrystalline layers and new devices and perform extended electrical and optical characterization of these layers.

Challenges in this part of the project are:


development of a physics-based model for charge carrier transport in polycrystalline III-N layers. TCAD simulations could be a part of the work as well.


development of novel polycrystalline III-N device concepts such as light-emitting diodes and power devices.


optical and electrical characterization of the envisaged devices

The project is financed by the Dutch Technology Foundation STW ( via the Open Technology Program (OTP). The research will be carried out at the University of Twente, Enschede, The Netherlands. The PhD student will be under guidance of several supervisors (Dr. Alexey Kovalgin, Dr. Ray Hueting, Prof. Dr. Jurriaan Schmitz and Prof. Dr. Dirk Gravesteijn) of the University of Twente. The research program is under the close attention of NXP, Philips, and ASM International.


We are looking for a highly motivated and enthusiastic researcher (F/M) with a M.Sc. degree in electrical engineering, nanotechnology, applied physics or a related topic, with excellent theoretical and experimental skills. Proven affinity with semiconductors is necessary. We seek candidates with good team spirit, who like to work in an internationally oriented environment. Fluency in English is a requirement. An interview will be part of the selection procedure. Applications should include an application/motivation letter, emphasizing your specific interest, qualifications and motivation to apply for this position, a detailed CV (resume), a publication list, contact details of at least 2 referees, and an academic transcript of B.Sc. and M.Sc. education. A TOEFL or IELTS score is generally requested to verify sufficient mastering of the English language. You can electronically apply for this position before August, 15th 2015. For more information please contact our secretary of Semiconductor Components Group Mrs. Remke Assink at

Conditions of employment

We offer an interesting temporary research position in a dynamic and international environment, with the benefits of an industrial laboratory as well as academic research. You will be appointed for a period of four years as a temporary research employee, as detailed in the collective labour agreement of the Dutch Universities. A training program is part of the agreement. You and your supervisor will make up a plan for the additional education and supervising that you specifically need. This plan also defines which teaching activities you will be responsible for (expected to take 10%-20% of your time).


The University of Twente. We stand for life sciences and technology. High tech and human touch. Education and research that matter. New technology which drives change, innovation and progress in society. The University of Twente is the only campus university in the Netherlands; divided over six faculties we provide more than fifty educational programmes. The University of Twente has a strong focus on personal development and talented researchers are given scope for carrying out pioneering research.

The faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) comprises three disciplines that shape Information and Communication Technology. ICT is more than communication. In almost every product we use mathematics, electronics and computer technology and ICT now contributes to all of societies' activities. The faculty works together intensively with industrial partners and researchers in the Netherlands and abroad and conducts extensive research for external commissioning parties and funders. The research which enjoys a high profile both at home and internationally, has been accommodated in the multidisciplinary research institutes MESA+, CTIT and MIRA.
