Amsterdam researchers have developed a novel technique for spatially controlled patterning of semiconductors with tuneable optoelectronic properties. As a proof of principle, Lukas Helmbrecht and Wim Noorduin ‘painted’ a portrait of Marie Curie in a perovskite semiconductor layer. Both researchers work at the AMOLF research institute at Amsterdam Science Park. Wim Noorduin is professor of Self-Organising Matter at the University of Amsterdam’s Van ‘t Hoff Institute for Molecular Sciences. Lukas Helmbrecht obtained his PhD at UvA under Noorduin’s supervision. The results of their research are published this week in the journal ‘Advanced Materials’.
In the paper, Helmbrecht and Noorduin present their novel ion-exchange lithography technique that takes on the fundamental challenge of patterning semiconductor materials with different properties in a single film. This patterning is essential for the development of next‐generation (opto)electronic

Ilse Denekamp, a PhD student working under the supervision of Prof. Gadi Rothenberg at the University of Amsterdam’s Van ‘t Hoff Institute for Molecular Sciences, has ‘translated’ her PhD research in a short film. The one-minute animation highlights the advantages of novel tailor-made single-site catalytic materials for heterogeneous catalysis. Ilse Denekamp will defend her PhD thesis on 7 April.
Using a combination of computer-animation techniques, Denekamp produced an ‘instruction manual’ explaining her research in the language of Lego. In her PhD thesis she describes a building-block approach for making covalently-bonded polymers with tailored catalytic properties. These polymers are stable up to 400 °C, combining the specific metal sites of organometallic complexes with the stability and ease of separation of solid catalysts. While developing these materials, Denekamp and co-workers used Lego bricks as models. This gave her the idea of prese
