Understanding photogenerated carrier transport in 2D perovskites, especially surface states, is challenging with conventional time-resolved techniques. Scientists at KAUST utilized scanning ultrafast electron microscopy (SUEM) with groundbreaking surface sensitivity to disclose carrier diffusion rates of ~30 cm虏/s for n=1, 180 cm虏/s for n=2, and 470 cm虏/s for n=3, which are notably higher than bulk. This highlights the SUEM鈥檚 potential for advancing the understanding of carrier dynamics. Density Functional Theory (DFT) confirms broader carrier transmission channels at the surface, offering key insights for optimizing 2D perovskite optoelectronic devices.

The transplutonium actinides are highly radioactive and rare, making them difficult to study. To examine their chemical properties, researchers typically use non-radioactive lanthanides as surrogates. In this study, scientists streamlined the synthesis of transplutonium actinide compounds, which allowed for more accurate direct comparisons of lanthanides and heavy actinide compounds, showing that transplutonium actinides have truly unique properties.
