Are you passionate about advancing the frontiers of nanophotonics and eager to contribute to the next generation of optoelectronic devices? If you are seeking an international research experience that bridges fundamental science and real-world applications, this joint PhD position in silicon metasurfaces for enhanced light extraction in LEDs may be the perfect opportunity for you.
About the University or Research Institute
This prestigious joint PhD program is offered collaboratively by the University of Hull in the United Kingdom and the Université de Technologie de Troyes (UTT) in France. The University of Hull, located in the vibrant city of Hull in northern England, is recognized for its strong research in physical sciences, engineering, and nanotechnology. With a commitment to fostering innovation and interdisciplinary collaboration, Hull provides access to world-class facilities, including the Viper High Performance Computing cluster, and a supportive academic environment.
The Université de Technologie de Troyes, situated in the picturesque Champagne region of France, is renowned for its excellence in engineering, photonics, and materials science. UTT’s state-of-the-art laboratories and its L2n (Light, Nanomaterials, Nanotechnologies) research group are at the forefront of nanophotonics research in Europe. As a PhD candidate, you will benefit from the dynamic research cultures of both institutions, spending half of your time in each country, and gaining exposure to diverse scientific communities and cutting-edge facilities.
Studying in both the UK and France offers exceptional academic, cultural, and professional benefits. You will have the chance to build an international network, experience two different research systems, and enhance your language and intercultural skills—qualities highly valued in today’s global scientific landscape.
Research Topic and Significance
The focus of this PhD project is the fabrication and characterization of silicon metasurfaces to enhance light extraction from organic light-emitting diodes (OLEDs) and related devices. Metasurfaces—engineered two-dimensional nanostructures—enable precise manipulation of electromagnetic waves, offering transformative potential for optoelectronics.
Silicon-based metasurfaces are particularly promising due to their low optical losses, high refractive index, and compatibility with established manufacturing techniques. By leveraging Mie resonances and advanced nanofabrication, the project aims to modulate and direct light emission in OLEDs, thereby improving efficiency, brightness, and device lifetime.
This research is highly relevant in today’s context, as the demand for energy-efficient lighting and display technologies continues to grow. Enhanced light extraction not only boosts device performance but also reduces power consumption and operational degradation, contributing to sustainable and high-performance optoelectronics.
Project Details
The METALED project follows a comprehensive methodology combining simulation, fabrication, and experimental characterization:
– Numerical simulations will be conducted using advanced software tools (Comsol® and Lumerical®), leveraging high-performance computing resources at both institutions.
– Fabrication of silicon metasurfaces will take place at UTT using electron lithography and reactive ion etching, with alternative approaches such as interferential laser lithography also explored.
– The Nano3 research group at the University of Hull will oversee the deposition of fluorescent organic molecules and perform optical characterization using spectroscopy, fluorescence lifetime measurements, and Fourier plane imaging.
– Integration of metasurfaces into OLED devices will be carried out in collaboration with the L2n group in Reims, with surface-enhanced Raman spectroscopy (SERS) employed to assess the impact on organic semiconductor degradation.
This joint project is supervised by leading experts in the field, including Dr. Anne-Laure Baudrion (UTT) and Dr. Jean-Sebastien Bouillard (University of Hull). For more information about the research groups and facilities, prospective candidates can explore the following links:
