PERSEPHONe (PERovskite SEmiconductors for PHOtoNics) is a coordinated training network which wants to generate new skills, knowledge and innovation for the development of a novel technological platform for photonics based on metal-halide perovskite semiconductors. These materials have impressive optoelectronic properties and they can be engineered to achieve a large set of functionalities whose integration could lead to important improvement to Silicon photonics, Silicon (Oxy)Nitride and other established technological platforms. PERSEPHONe is a multidisciplinary and intersectoral effort which sees, in parallel, the development of perovskite materials, the development of photonic devices and the integration of such building blocks in integrated photonic circuits, with the intent to set the bases for a technology which is commercially viable. 8 academic and 5 industrial beneficiaries, from 7 different EU Countries and one EU-13 Country will train 14 ESRs, exposing them to a wide spectrum of expertise: materials synthesis, photonic (and optoelectronic) devices and integrated circuits fabrication, characterization, and modeling, upscaling and manufacturing together with a powerful set of soft skills. Each ESRs will learn how to deal with complex problems, acquiring broad competences and becoming highly adaptable. They will be aware of their skills and attitudes and spend them efficiently in both corporate and academic worlds, eventually reinforcing the European placement in the high tech market.
