Phys.org  October 11, 2024 Layered hybrid perovskites (LHPs) have emerged as promising reduced-dimensional semiconductors for next-generation photonic and energy applications where controlling the size, orientation, and distribution of quantum wells (QWs) is of paramount importance. A team of researchers in the US (North Carolina State University, Brookhaven National Laboratory) revealed that bulky molecular spacers act as crystal-terminating ligands to form colloidal nanoplatelets (NPLs) during early stages of LHP formation. They proved that NPLs ripen and grow, playing a decisive role in the time evolution of QW size, population distribution, and orientation. They demonstrated that antisolvent drip interrupts NPL ripening and […]
