#2DPERO - 2D Perovskites: Synthesis, Properties, and Applications

Description of topical focus

Two-dimensional (2D) perovskites are of great interest for a wide gamut of optoelectronic applications including photovoltaics, light emission, catalysis, or resistive memory. These phases are composed of slabs of metal-halide octahedra, which are separated by large, often organic, cations, to create a layered structure. The optoelectronic properties of 2D perovskites can be tailored by substituting the metal, halide, and spacer cations. For example, the emission color can be tuned across the visible spectrum by alloying the halides, or by changing the number of octahedral layers in the 2D slabs. Interestingly, different halides and spacer cations bestow specific mechanical properties on the 2D phases, and these mechanical properties in turn affect phase stability and optoelectronic behavior. Such tunability of the structure creates a large toolbox of functional properties, which can be tailored for a variety of applications. This symposium explores the synthesis, properties, and applications of layered metal halide perovskites. We invite contributions discussing novel 2D perovskite phases, challenges associated with growing 2D phases as thin films, structureproperty relationships, ferroic behavior, ion diffusion, thermoelectrics, unusual light emission, and other photophysics. A particular focus will lie on applications beyond photovoltaics, such as quantum information, random-access memory, or photodetection.
