Novel perovskite semiconductors promise photonic circuits, which can potentially trigger a technological revolution. In the new research project “PerovsKET – Improving the microstructure of perovskites via thermal nanoimprint as key technology for large scale perovskite optoelectronics”. AMO GmbH from Aachen, a team of the Bergische Universität Wuppertal (BUW, chair for electronic devices) and NB Technologies seated in Bonn are researching important basic technologies to combine the perovskite photonics with the world of silicon electronics. The project is funded by the European Regional Development Fund (ERDF) 2014-2020 and by the federal state North Rhine Westphalia for a duration of 3 years with a total budget of 1.5 Mio€.
AMO’s main tasks in the project are the research and fabrication of novel TensoStamps suitable to improve the micro-structure of perovskites, as well as the fabrication and characterization of optically pumped perovskite nano-lasers as a highly relevant application of the new materials and an ideal benchmark system for the aspired improvements.
Scanning electron micrographs of a MAPbI3 perovskite disk laser on a SiO2/Si substrate, which has reached a record low lasing threshold compared to other lasers integrated on chips. The intrinsic perovskite roughness leaves a lot of room for improvement within the PerovsKET project leading to even lower lasing thresholds.
