Researchers boosted exciton mobility approaching Mott-Ioffe-Regel Limit in Ruddlesden-Popper perovskite
Exciton transport in 2D perovskite plays a pivotal role for their optoelectronic performance. We reveal that the free exciton mobilities in exfoliated thin flakes can be improved from around 8 cm²V⁻¹s⁻¹ to 280 cm²V⁻¹s⁻¹ with PMMA network at the surface.
