Symposium on Light Emission and Photonics of Group IV Semiconductor Nanostructures (LPGN)

14th December 2022 


Co-sponsored by Nagoya University Institute for Advanced Research (IAR)




The symposium aims at presenting and discussing the state of the art and potential for applications of group IV semiconductor nanostructures, in the field of light emission and associated photonic functions. More precisely, discussions will involve various types of silicon nanostructures, such as individual nanocrystals, porous silicon, nanodot assemblies, and nanostructures of some group IV elements (Si, Ge, Sn). The potential of such nanostructures in diverse multidisciplinary fields, such as electronics, photonics, plasmonics, biology, or medicine, will be considered. The symposium will also aim at (i) estimating the most promising fields and routes for applications of silicon nanostructures in society, as well as (ii) identifying the fundamental aspects that still need to be clarified and ways to clear them.
