Quantum materials and emergent phenomena
When the sum is larger than the parts
We explore properties emerging from correlations between electrons within single materials, from superlattices or chains of nanoparticles, and from larger scale meso-structure. The aim is to find materials with unconventional properties that make them suitable for applications in, for example, semiconductor, quantum or energy technology.
Research areas:
- Aerosol-based nanoparticle generation
- Perovskite nanocrystal synthesis
- Correlated and magnetic materials
Aerosol-based nanoparticle generation
Aerosol-based methods, such as spark ablation, enables generation of nanoparticles with high-purity and controllable size, morphology, crystal structure and chemical composition on a large scale, at low costs, and in a safe and environmentally friendly way. Spark ablation also has superior capabilities for mixing different materials into single nanoparticles, forming single multielemental compositions, such as medium- and high-entropy alloys. We mainly focus on the design of magnetic and catalytic nanoparticle-based materials to understand how nanoparticle properties can be tuned to improve the magnetic and catalytic performance of such materials. We also employ a novel self-assembly approach to generate magnetic nano- and microstructures, e.g., for spintronics, magnetoresponsive materials, and catalysis.

Perovskite nanocrystal synthesis
We work on perfecting the synthesis of metal halide nanocrystals in perovskite and closely related structures. One focus is to produce wide-bandgap, lead-free, layered double perovskite nanocrystals for photocatalytic applications such as photoelectrochemical water splitting. Another focus is to produce self-assembled superstructures and use them as model systems in photophysics studies of collective light emission phenomena such as superfluorescence.
