Here, we aim to integrate advanced piezo-electric materials for fast and low power modulation.
In the project we will fabricate SiN integrated photonics with low-power modulation utilizing the high piezo-electronic coefficient of materials. New processing routes will be developed to integrate these materials with SiN waveguides.
We are looking for a PhD candidate to work on Ultra-low power phase modulator in silicon nitride. You will develop, optimise and apply nanofabrication techniques and thin film technologies to study modulation in silicon nitride devices. This work will be done in the UT’s Nanolab, using state of the art fabrication and analysis techniques.
Your home base will be within the Inorganic Materials Science group (IMS) chair [https://www.utwente.nl/en/tnw/ims/] in the MESA+ Institute for Nanotechnology at the University of Twente.
Your supervisor will be Prof. Guus Rijnders (IMS). We work closely together with our colleagues in the integrated photonics program.
We hope to fill this position in 2024.

About the department
IMS is a research group devoted to thin film growth studies, (nano)structuring techniques, and properties of complex materials, in particular oxides. It includes materials with diverse properties, like ferroelectrics, ferromagnetics and multiferroics, piezo’s, high-K dielectrics, transparent conducting oxides, non-linear optical materials, ion conductors, superconducting and related materials, and anti-reflection coatings. Its research field is focussed on thin films with modified properties by doping or by artificial layered structures and superstructures. Applications are found in, e.g., nano-electronics and spintronics, optical systems, fuel and solar cells, fluidics, bio-nano sensors.
About the organisation
The Faculty of Science & Technology (Technische Natuurwetenschappen, TNW) engages some 700 staff members and 2000 students in education and research on the cutting edge of chemical technology, applied physics and biomedical technology. Our fields of application include sustainable energy, process technology and materials science, nanotechnology and technical medicine. As part of a people-first tech university that aims to shape society, individuals and connections, our faculty works together intensively with industrial partners and researchers in the Netherlands and abroad, and conducts extensive research for external commissioning parties and funders. Our research has a high profile both in the Netherlands and internationally and is strengthened by the many young researchers working on innovative projects with as doctoral candidates and post-docs. It has been accommodated in three multidisciplinary UT research institutes: Mesa+ Institute, TechMed Centre and Digital Society Institute.
