Abstract

Self-Assembled Perovskite Nanoislands In article number 2105542, Jung-Ho Yun, Jae Sung Yun, Lianzhou Wang, and co-workers report an energetic surface engineering strategy to restructure non-uniform CH3NH3PbI3 perovskite crystal surfaces. By thermally evaporating energetic CsI on single crystal surfaces, a unique nano-island structure is formed through a cation interdiffusion process. This morphology induces a gradient band bending, which increases the charge carrier mobility by 60.
