Structural Evolution of Layered Hybrid Lead Iodide Perovskites in Colloidal Dispersions

Autor: Naveen R. Venkatesan, Ram Seshadri, Noah C Smith, Jiamin Zhang, Clayton J. Dahlman, Matthew E. Helgeson, Patrick T. Corona, Lingling Mao, Michael L. Chabinyc, Rhys M. Kennard

Publikováno v: ACS Nano, vol 14, iss 9

Controlling the structure of layered hybrid metal halide perovskites, such as the Ruddlesden-Popper (R-P) phases, is challenging because of their tendency to form mixtures of varying composition. Colloidal growth techniques, such as antisolvent preci

Even-Parity Self-Trapped Excitons Lead to Magnetic Dipole Radiation in Two-Dimensional Lead Halide Perovskites

Autor: Jon A. Schuller, Rhys M. Kennard, Xinhong Du, Clayton J. Dahlman, Ryan A. DeCrescent, Michael L. Chabinyc, Naveen R. Venkatesan

Publikováno v: ACS nano. 14(7)

Recently, unconventional bright magnetic dipole (MD) radiation was observed from two-dimensional (2D) hybrid organic-inorganic perovskites (HOIPs). According to commonly accepted HOIP band structure calculations, such MD light emission from the groun

Light-matter interactions in semiconductor systems are uniformly treated within the electric dipole (ED) approximation, as multipolar interactions are considered "forbidden". Here, we demonstrate that this approximation inadequately describes light e
