    • Bright Excitonic Fine Structure in Metal-Halide Perovskites: From Two-Dimensional to Bulk 

      Posmyk, Katarzyna; Zawadzka, Natalia; Łucja Kipczak; Dyksik, Mateusz; Surrente, Alessandro; e.a. (American Chemical Society, 2024-02-07)
      The optical response of two-dimensional (2D) perovskites, often referred to as natural quantum wells, is primarily governed by excitons, whose properties can be readily tuned by adjusting the perovskite layer thickness. ...

    • Persistent enhancement of exciton diffusivity in CsPbBr3 nanocrystal solids 

      Shcherbakov-Wu, Wenbi; Saris, Seryio; Sheehan, Thomas John; Wong, Narumi Nagaya; Powers, Eric R; e.a. (American Association for the Advancement of Science, 2024-02-21)
      In semiconductors, exciton or charge carrier diffusivity is typically described as an inherent material property. Here, we show that the transport of excitons among CsPbBr3 perovskite nanocrystals (NCs) depends markedly ...

    • All-Perovskite Multicomponent Nanocrystal Superlattices 

      Sekh, Taras V; Cherniukh, Ihor; Kobiyama, Etsuki; Sheehan, Thomas J; Manoli, Andreas; e.a. (American Chemical Society, 2024-03-06)
      Nanocrystal superlattices (NC SLs) have long been sought as promising metamaterials, with nanoscale-engineered properties arising from collective and synergistic effects among the constituent building blocks. Lead halide ...
