PHD Position Excitons and Light-matter Interactions in Perovskite-tmd Structures

NWO-I NWO-I Intranet PhD Position Excitons and Light-Matter interactions in Perovskite-TMD Structures Nijmegen PhD Position: Excitons and Light-Matter interactions in Perovskite-TMD Structures in High Magnetic Fields Do you have a strong interest in experimental condensed matter physics, nanomaterials, and optoelectronics? We are looking for a highly motivated PhD candidate to join our research programme on 2D materials and their heterostructures. In this project, you will explore light-matter interaction in two-dimensional systems in high magnetic fields, with the goal of understanding and engineering novel optoelectronic functionalities. The research combines materials synthesis, heterostructure assembly, advanced spectroscopy, and device fabrication. As a PhD candidate, you will: • Synthesize and characterize 2D materials, for instance, layered halide perovskite semiconductors. • Fabricate and assemble van der Waals heterostructures combining halide perovskites with transition metal dichalcogenides (TMDs). • Investigate their optoelectronic properties, including excitonic effects and charge carrier dynamics, in high magnetic fields and under optical/THz excitation. • Probe light-induced excitations and their coupling to electronic and excitonic states in high magnetic fields. • Develop and test photodetectors and optoelectronic devices based on these materials. You will work in a collaborative and interdisciplinary environment, interacting with PhD candidates, postdoctoral researchers, scientific and technical staff, and contributing to joint experimental campaigns. You may also contribute to teaching activities within Radboud university and support for guest researchers of the research facility of HFML-FELIX (maximum of 10% of your time). This project aims to bridge fundamental physics of two-dimensional semiconductors with next-generation optoelectronic applications, including photodetection and energy-efficient devices. Your working environment The position is hosted by Radboud University and embedded in the PhD Graduate School of the Institute for Molecules and Materials . You will be based at HFML-FELIX, working in the Soft Condensed Matter & Nanomaterials group, while maintaining active connections with a network of research institutes across the Netherlands. You will be embedded in a dynamic and interdisciplinary research environment focusing on quantum and functional materials. The group combines expertise in 2D materials, perovskite semiconductors, and advanced optoelectronic characterization, with access to state-of-the-art facilities for high magnetic field experiments, spectroscopy, and nanofabrication. The research environment encourages close collaboration between experimentalists and theoreticians, alongside strong engagement with international research infrastructures and external guest researchers. This collaborative setting enables cutting-edge studies of light-matter interactions, excitonic phenomena, and device functionalities in low-dimensional systems. What you bring • You have a Master's degree in experimental physics , materials science, nanotechnology, or a related field. • You have a strong interest in condensed matter physics , low-dimensional systems, and optoelectronics and are motivated to work at the interface of fundamental research and device development. • Exposure to any of the following areas is a plus: • Nanomaterials synthesis (e.g. perovskites, 2D materials) • Optical spectroscopy (photoluminescence, absorption, THz spectroscopy) • Device fabrication (cleanroom techniques, lithography) • Low-temperature or high magnetic field experiments • You have good communication skills and a strong command of English language (written and spoken) at an academic level. What we offer • A challenging and meaningful position for 40 hours per week. • A collegial team in which we help and support each other. • A four year PhD position, with a go/no-go decision to be made after a year. • A training program for PhD candidates within the Radboud University IMM Graduate School . • A gross full-time monthly salary of €3,115, which will increase every year, in accordance with the salary scales for research trainees (OIOs) of the collective labour agreement for research institutions, plus holiday pay and a year-end bonus. • Our excellent secondary employment conditions can be found here , such as the option to choose more than 8 weeks of holiday per year.
