Two Ph.D. students

The group of Semiconductor Components has two open vacancies for Ph.D. students. One position is related to low-temperature deposition of dielectrics for integrated optics applications. The other position deals with the modeling of silicon-based light emitters. The group of Semiconductor Components (http://www.sc.el.utwente.nl) at the University of Twente (Netherlands) is part of the Faculty of Electrical Engineering, Mathematics and Computer Science and the MESA+ Research Institute. 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. he first Ph.D. student will use a custom-built, modern CVD system to deposit high-quality dielectric layers. These layers will be patterned and characterized for their optical properties, using in-situ and ex-situ measurements. Supervision will be given by experts in CVD and experts in optical characterization of the University of Twente. The student will cooperate closely with staff of the research group of Integrated Optics (IOMS). The aim is to develop waveguides and ring resonating structures at much lower process temperatures than presently common, to allow CMOS wafer post-processing. The second Ph.D. student will study band-to-band light emission from silicon. This emission behaviour is not well understood and only recently, researchers have made silicon LEDs with this principle, that have a reasonable power efficiency. The study will involve the development and testing of new models describing the light generation process; and a verification of these models by electrical and optical measurements. For both, the infrastructure (device modeling software, optical and electrical testing equipment, light-emitting devices) is already in place. The student will work closely with a Ph.D. student responsible for the realization of new silicon LED’s.

We ask

A M.Sc. (or equivalent) in (applied) physics, materials science or electrical engineering; proven affinity with microtechnology (first position) or semiconductor modeling (second position); good mastering of the English language; and good communication skills. Good study results and international experience are required.

We offer

The Ph.D. students will be appointed as a temporary employee of the University, for a period of four years with a salary starting at 1813 € gross per month. The labor conditions are described in the Collective Labor Agreement of the Dutch Universities. We offer a world-class scientific environment for multidisciplinary research with a wide range of educational possibilities.
