New insight into carrier transport in 2D layered perovskites

2D layered halide perovskites exhibit anisotropic carrier transport. Using scanning photocurrent microscopy, in this issue of Chem, Shrestha et al. report novel findings in 2D layered Ruddlesden-Popper perovskites, including a long carrier in-plane diffusion length and exciton behavior and dissociation, unveiling new insight not previously obtained through spectroscopic techniques.
