Project information

The goal of the project is to initially explore a concept for a novel 3D printer that would allow the local and 3D-structured deposition of different materials. The principle is based on a gas phase reaction, which is triggered by a high electric field. The field is generated with an applied voltage and localized with a nanoscale tip, which can be scanned across the substrate at a small distance in a controlled manner. This should enable the 3D-structured deposition of numerous materials (metals, semiconductors, insulators) in the nanometer range. Applications for this nano-printing technology would include nanoscale semiconductor components (FETs, LEDs, quantum dots, nanowires), quantum structures, plasmonics, the generation of safety features, the synthesis of novel catalysts and many more.
