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
