Ternary-blend Halide Perovskites for Thin-Film Photonic Devices: From Photodetectors to LEDs and Lasers
PhD - Leuven | Just now
Can a new perovskite composition become the foundation for tomorrow's imagers, LEDs, and lasers? Metal-halide perovskites are among the most promising materials for next-generation photonic devices, combining tunable optical properties with scalable thin-film processing. Recent advances have demonstrated high-performance photodetectors, imagers, and light-emitting devices, yet key questions remain regarding the composition regimes that can simultaneously deliver high performance, long-term stability, and ultimately electrically driven laser operation.
This PhD will explore the largely uncharted composition space of ternary-blend halide perovskites, where small changes in composition can lead to major changes in material and device performance. By systematically varying composition and processing conditions, the project will investigate how these materials influence light detection, light emission, efficiency, and stability. The aim is to identify and understand new composition regimes for high-performance photodetectors, imagers, LEDs, and lasers.
The work combines material development, thin-film device fabrication, advanced optical and electrical characterization, and modelling. The candidate will be part of a team that has contributed to recent advances in perovskite optoelectronics and will have access to state-of-the-art fabrication and characterization infrastructure. By working across the full innovation chain, from materials to functional photonic devices, the candidate will establish design rules for next-generation perovskite photonics while gaining broad expertise at the intersection of materials science, photonics, and semiconductor technology. The results could contribute to future sensing, imaging, communication, and optical interconnect technologies.
