Two-dimensional (2D) hybrid organic-inorganic metal halide perovskites offer enhanced stability for perovskite-based applications. Their crystal structure's soft and ionic nature gives rise to strong interaction between charge carriers and ionic rearrangements. Here, we investigate the interaction of photogenerated electrons and ionic polarizations in single-crystal 2D perovskite butylammonium lead iodide (BAPI), varying the inorganic lamellae thickness in the 2D single crystals.

- * The process involves the thermal decomposition of ligands, which modifies the distance between NPLs and affects their electronic coupling strength.
- * Enhanced electronic coupling results in increased free carrier generation and improved short-range mobility, providing a clear method for optimizing NPLs for functional optoelectronic devices through thermal treatments.
Highly mobile hot charge carriers are a prerequisite for efficient hot carrier optoelectronics requiring long-range hot carrier transport. However, hot carriers are typically much less mobile than cold ones because of carrier-phonon scattering. Here, we report enhanced hot carrier mobility in CsAgBiBr double perovskite.
