Tóm tắt

2D hybrid perovskites have attracted great interest due to their promising potential in photodetectors. The phase structure, dielectric, and excitonic properties in 2D perovskites play a pivotal role in the performance of the corresponding optoelectronic device. Here a lattice anchoring method is demonstrated to boost carrier mobility in 2D perovskites by tailoring large organic spacer cation layers. By tuning the electron-withdrawing halogens at the 4-position of the phenyl group in the widely investigated component C
