Symposium ET05—Fundamental Aspects of Halide Perovskite (Opto)electronics and Beyond
Halide perovskites, in particular hybrid organic-inorganic halide perovskites, have recently emerged as a new family of materials that are revolutionizing the field of (opto)electronics such as solar cells, light-emitting diodes, photo-/radiation detectors, transistors, and memristors. These materials are surprising the researchers not just by the outstanding device performance, but also by many exceptional phenomena such as fast ion migration and giant light/atmospheric effects among them. While the technological development of (opto)electronics based on halide perovskites has been unprecedentedly swift within the past few years, fundamental understandings in physics, chemistry, and materials science of these truly new materials are relatively behind. It is unambiguous that the exploration of these fundamental aspects can be the key to reaching/breaking the limit of the attainable performance in perovskite-based (opto)electronics in the future. Further, the particular physics, chemistry and materials science gained from these truly new materials are likely to lead to the discovery of emerging materials properties and the invention of new-type devices. In this context, there is a surge of ongoing research activities in this direction all over the world. The involved research topics include but are not limited to materials theory, crystal chemistry, photophysics, electron/ion transport, growth mechanisms, characterization, nano-/quantum science, and their implications to the future development of perovskite-based (opto)electronics. This proposed symposium will cover these topics, and aim to provide an international platform for the researchers in the field of halide perovskites to share their fundamental understandings/findings. The outcome of this symposium will in turn stimulate/accelerate the board efforts in developing high-performance perovskite-based (opto)electronics and new perovskite-based applications.
