Semiconductors are at the heart of various modern technologies that are extensively used in our daily lives. Classical bulk and epitaxial semiconductors are often produced by high-temperature, high-vacuum processes that consume significant energy and lack design freedom. Solution-processable semiconducting materials with nanoscale morphology, such as colloidal quantum dots, organics,and perovskites have received intense interest to address this problem. Their wide tunability in structure, dimensionality, optical and electronic properties allow for tailoring the materials’ functionalities to fulfill different needs. Moreover, they can be deposited strain-free allowing large versatility to combine their functions with integrated platforms for mass production, such as silicon photonics. This booming class of materials also benefits from a vast spectral range covering from mid-IR to UV. As a consequence, massive effort has been put into integrating these materials into the latest generation of photonic devices, including solar cells, light-emitting diodes, photodetectors, single-photon sources, scintillators, lab-on-chips, and optical and quantum communication systems, achieving performances comparable to commercially available counterparts.
In spite of the many advantages, implementation of solution fabricated electronics still faces significant challenges that need to be addressed, such as operational stability of devices, optimization of interfaces between materials, and integration of such devices on chips. Given the intimate link between materials and photonics in all the application domains sketched above, this requires concerted efforts of different communities combining advanced synthetic approaches, interface engineering, device integration techniques, and in-depth studies on materials and devices using spectroscopy, microscopy and machine learning-based computational tools to provide insights on how to control light, heat, and carrier management.
This symposium will hence serve as a unique stimulating platform to promote multi-disciplinary discussions for addressing the current challenges. In order to achieve this, the symposium will bring together world-renowned leaders in the different fields, spanning from experimentalists to theorists and device engineers. To promote multifaceted debates, sessions will be dedicated to solution-based chemistry, nanomaterials characterization, theoretical modeling, device integration, and lab-to-industry process scalability, thus expecting to attract interest not only in academia but also in the industry.
