The formed 2D perovskites feature a highly ordered orientation normal to the substrate and a pure n = 1 phase, which efficiently passivates surface defects of the as-prepared perovskite films and improves the energy level alignment between the perovskite film and electron transport layer. Consequently...

We directly visualize photo-generated carrier transport over both spatial and temporal dimensions on the top surface of 2D perovskites with varying inorganic perovskite layer thicknesses (n=1, 2, and 3). The results reveal the photo-induced surface carrier diffusion rates of ~30cm2路s-1forn=1,...
For n = 1, a pure 2D perovskite structure of type (RNH3)2MX4 can be achieved and for n = ∞, a close to 3D perovskite structure can be achieved. Thus RP perovskites demonstrate optoelectronic properties which comprise of wide range of properties from 2 to 3D perovskites1,18,...

Organic spacer cations in layered 2D (A(1))(2)(A(2))(n)-1BnX3n+1 (where A(1) is an organic cation acting as a spacer between the perovskite layers, A(2) is a monovalent cation, e.g., Cs+,CH3NH3+, CH(NH2)(2)(+)) perovskite materials improve the long-term stability of ...
