Semiconducting Tin and Lead Iodide Perovskites with Organic Cations: Phase Transitions, High Mobilities, and Near-Infrared Photoluminescent Properties

Constantinos C. Stoumpos, Christos D. Malliakas, Mercouri G. Kanatzidis

Short summary

Researchers synthesized a series of hybrid metal iodide perovskites (AMI3) with organic cations (methylammonium or formamidinium) and tin or lead, revealing tunable band gaps (1.25-1.75 eV), intense near-infrared photoluminescence (700-1000 nm), and high electron/hole mobilities exceeding 2000 cm²/Vs and 300 cm²/Vs, respectively.
